Remember that a chi-square test is used to help determine if observed results are in line with expected results, and to rule out that observations are due to chance. This means that a chi-square statistic is a test that measures how a model compares to actual observed data.

The data used in calculating a chi-square statistic must be:

1. random

2. raw

3. mutually exclusive

4. drawn from independent variables,

The radical form of the number √ ( - 27 ) is given by the equation A = 3i√3

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the number be represented as n

The value of n = √( -27 )

Now , the value -1 can be represented as the complex number i

where i² = 1

So , the number n can be written as

A = √ ( 3i )² 3

A = √9i² (3)

A = √27i²

A = √-27

On simplifying the equation , we get

a. The probability of getting exactly 426 girls in 846 births is approximately 0.078.

b. Getting 426 or more girls has a probability of only approximately 0.195.

c. The probability from part (b) is more relevant for trying to determine whether the gender-selection technique is effective.

d. More data or a different approach may be needed to determine the effectiveness of the gender-selection technique.

a. To find the probability of getting exactly 426 girls in 846 births, we can use the binomial distribution formula, which is:

P(X = x) = nCx * p^x * (1-p)^(n-x)

where n is the total number of births, x is the number of baby girls, p is the probability of a baby being a girl (0.5 in this case), and nCx is the binomial coefficient, which can be calculated using the formula nCx = n! / (x!(n-x)!).

Plugging in the given values, we get:

P(X = 426) = 846C426 * (0.5)^426 * (0.5)^(846-426) ≈ 0.078

b. To find the probability of getting 426 or more girls in 846 births, we can use the same binomial distribution formula, but we need to add up the probabilities of getting 426, 427, ..., 846 girls. This can be expressed as:

P(X >= 426) = P(X = 426) + P(X = 427) + ... + P(X = 846)

To avoid calculating the probability for all possible values of X, we can use the complement of this probability, which is the probability of getting 425 or fewer girls in 846 births:

P(X <= 425) = P(X = 0) + P(X = 1) + ... + P(X = 425)

We can use a binomial calculator or a normal distribution approximation to find this probability. Using a normal distribution approximation, we can use the mean and standard deviation of the binomial distribution, which are:

man = n * p = 846 * 0.5 = 423

standard deviation = sqrt(n * p * (1-p)) = sqrt(846 * 0.5 * 0.5) ≈ 18.34

Then, we can standardize the value of 425 using the z-score formula:

z = (425 - mean) / standard deviation ≈ 0.86

Using a standard normal distribution table, we can find the probability of getting a z-score less than or equal to 0.86, which is approximately 0.805. Therefore,

P(X <= 425) ≈ 0.805

Finally, we can find the probability of getting 426 or more girls as:

P(X >= 426) = 1 - P(X <= 425) ≈ 0.195

If we assume that boys and girls are equally likely, then getting exactly 426 girls in 846 births may not be unusually high since it has a probability of approximately 0.078. which could be considered unusual if he gender-selection technique is not effective.

c.as it considers the probability of getting 426 or more girls in 846 births, which is an indication of whether the technique is actually effective in increasing the likelihood of having a girl.

d. Based on the results, it does not appear that the gender-selection technique is very effective, as the probability of getting 426 or more girls in 846 births is only approximately 0.195, which is not significantly higher than the probability of getting exactly 426 girls by chance (approximately 0.078).

The probability that the residents own 2 cars and have an income over $50,000 a year is 0.35.

According to the survey, the probability that the residents of a household own 2 cars given an annual household income over $50,000 is 70%. Additionally, 50% of the households surveyed had incomes over $50,000 and 65% had 2 cars. To calculate the probability that the residents of a household own 2 cars and have an income over $50,000 a year, we can use conditional probability.

Let A represent the event of owning 2 cars and B represent the event of having an income over $50,000. We need to find P(A ∩ B), which is the probability of both events occurring.

Using the formula P(A ∩ B) = P(A | B) * P(B), we can substitute the given values: P(A | B) = 0.70 and P(B) = 0.50.

Therefore, P(A ∩ B) = 0.70 * 0.50 = 0.35. Thus, the probability is 0.35.

The number of possible permutations of 8 objects taken 3 at a time is 336.

The formula to calculate the permutation of 'n' object taken 'r' at a time is \(P_{r}=\dfrac{n!}{(n-1)!}\).

The formula for calculating the permutation is \(P_{r}=\dfrac{n!}{(n-r)!}\) where 'n' is the number of distinct objects taken 'r' at a time.

Thus we will substitute n=8 and r=3, we will get

Answer:

\(8i^{22}\) - 1

Explanation:

It's actually quite easy to tell which simplifies to a real number without working out the problem.

\(i^{2}\) = -1

Any imaginary number with an even exponent is simplified to a real number. If it has an odd exponent, it cannot be simplified to a real number.

Some tips for fully solving the expression:

If the exponent is divisible by 4, then don't change the sign of the coefficient. You're just multiplying it by 1 because \(i^{4}\) = \((i^{2})^{2}\) = \((-1)^{2}\) = 1

If the exponent is divisible by 2, change the sign of the coefficient because you're multiplying it by -1.

To calculate the probability that at least two people in a class of 30 share the same birthday, we can use the complement rule, which states that the probability of an event happening is equal to one minus the probability of the event not happening.

If we assume that birthdays are uniformly distributed throughout the year (i.e., each day is equally likely to be someone's birthday), then the probability that no two people in the class share the same birthday is:

365/365 * 364/365 * 363/365 * ... * 336/365

This is because the first person can have any birthday (probability of 365/365), the second person must have a different birthday (probability of 364/365), the third person must have a different birthday than the first two (probability of 363/365), and so on, up to the 30th person, who must have a different birthday than the first 29 (probability of 336/365).

Calculating this probability gives us:

(365/365) * (364/365) * (363/365) * ... * (336/365) ≈ 0.2937

So the probability that no two people in the class share the same birthday is approximately 0.2937.

Using the complement rule, the probability that at least two people in the class share the same birthday is:

1 - 0.2937 = 0.7063

Therefore, the probability that at least two people in a class of 30 share the same birthday is approximately 0.7063, or 70.63%.

Many different fish species periodically migrate over distances ranging from a few meters to many thousands of kilometres, and they do so on cycles that can last anywhere between a day and an entire year or more.

In 3 years, Aubrey will be able to spend $106.08 on a new bicycle.

First we can use the formula for compound interest:

A = P * (1 + r/n)^(nt)

Where:

A = final amount (balance)

P = principal (starting amount) = $100.00

r = interest rate as a decimal = 2% = 0.02

n = number of times per year that the interest is compounded = 1 (annually)

t = time in years = 3

Plugging in these values, we get:

A = $100.00 * (1 + 0.02/1)^(1 * 3)

A = $100.00 * (1.02)^3

A = $100.00 * 1.0608

Converting volume measurements from milliliters to ounces can be a bit tricky. However, with a little bit of math, it's easy to figure out how many ounces are in a given number of milliliters.

First, it's important to understand the relationship between milliliters and ounces. One ounce is equal to approximately 29.5735 milliliters. So, to convert milliliters to ounces, you simply need to divide the number of milliliters by 29.5735.

For example,

if you have 400 milliliters, you would divide 400 by 29.5735 to find that there are approximately 13.5277 ounces in 400 milliliters.
