22. In a study was done on 136 subjects with syncope or near syncope were studied. Syncope is the temporary loss of consciousness due to a sudden decline in blood flow to the brain. Of these subjects, 75 also reported having cardiovascular disease. Construct a 90,95, 99 percent confidence interval for the population proportion of subjects with syncope or near syncope who also have cardiovascular disease.

Answers

Answer 1

The main answer is that the confidence intervals for the population proportion of subjects with syncope or near syncope who also have cardiovascular disease, at 90%, 95%, and 99% confidence levels, are as follows:

90% Confidence Interval: Approximately 51.84% to 70.53%

95% Confidence Interval: Approximately 49.77% to 72.60%

99% Confidence Interval: Approximately 46.48% to 76.89%

In the study, out of the 136 subjects with syncope or near syncope, 75 reported having cardiovascular disease.

To construct the confidence intervals, we can use the formula for a proportion's confidence interval. The formula is based on the normal distribution assumption when sample size is large enough, which is satisfied here.

By plugging in the sample proportion (75/136) and the appropriate critical values based on the desired confidence level (1.645 for 90%, 1.96 for 95%, and 2.576 for 99%), we can calculate the lower and upper bounds for each confidence interval.

These confidence intervals provide an estimate of the likely range within which the true population proportion lies.

For example, with 95% confidence, we can say that we are 95% confident that the true proportion of subjects with syncope or near syncope who also have cardiovascular disease falls between approximately 49.77% and 72.60%.

The wider the confidence interval, the lower the precision of the estimate, but the higher the level of confidence.

Answers

Answer:

This is pretty simple, it tells you that two tickets are worth $18, to figure out how much one would cost you just divide 18/2 and that would equal $9. So Your answer would be Each ticket sold yields $9 of profit.

Here, Let, Number of Ticket = x

Sold profit = y

Then, relation would be: 18/2 = 9

y = 9x

In short, Your Answer would be Option B) "Each ticket sold yields $9 of profit"

How to determine the axis of symmetry and vertex of a quadratic function?

In Mathematics, the axis of symmetry of a quadratic function can be calculated by using this mathematical equation:

Axis of symmetry = -b/2a

Where:

a and b represents the coefficients of the first and second term in the quadratic function.

For the given quadratic function f(x) = x² – 2x – 6, we have:

a = 1, b = -2, and c = -6

Axis of symmetry, Xmax = -b/2a

Axis of symmetry, Xmax = -(-2)/2(1)

Axis of symmetry, Xmax = 2/2

Axis of symmetry, Xmax = 1.

Next, we would determine vertex as follows;

f(x) = x² – 2x – 6

f(x) = 1² – 2(1) – 6

f(x) = -7.

Now, we can write quadratic function in vertex form;

f(x) = a(x - h)² + k

f(x) = (x - 1)² - 7

Write the equation of a rational function that has been reflected, shifted down 6, right 8, and stretched by a factor of 4.

Answers

To write the equation of a rational function that has been reflected, shifted 6 down, 8 to the right and stretched by a factor of 4, we have to start with the basic rational function which is:

f(x)= 1/xThe reflected function we multiply it by -1 resulting in: g(x)= -1/xHow to shift a function?

To shift it down by 6, we must subtract 6 from the function, so we have:

h(x) = -1/x-6

To shift the function to the right by 8, we substitute x for (x-8), finding this result:

i(x)= -1/(x-8)-6

To stretch the function by a factor of 4, we have to multiply the denominator by 4, which will result in:

j(x)= -1/4(x-8))-6

Therefore, the equation of the rational function will be:

j(x)= -1/(4(x-8)) -6

On solving the given equation, we have - 125 adult tickets and 179= children tickets.

What exactly is an equation?

An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated by the symbol "equal."

301= 104

6.40 =2.25

4.00=1.75

Suppose the number of adult ticket bought =x

And number of children tickets bought = (301-x).

equation is

6.40(x) + 4(301-x) = 1504

6.40x + 1204 - 4x = 1504

As given in the question,

Percent of adults are concerned = 37%

Percent of adults are not concerned = (100 -37)%

= 63%

1 - p = 0.63
