A local police chief claims that about 51% of all drug related arrests are ever prosecuted. A sample of 900 arrests shows that 47% of the arrests were prosecuted. Is there sufficient evidence at the 0.01 level to refute the chief's claim? State the null and alternative hypotheses for the above scenario.
Answers
Answer:
The null hypothesis is \(H_0: p = 0.51\).
The alternate hypothesis is \(H_1: p \neq 0.51\).
The p-value of the test is 0.0164 > 0.01, which means that there is not sufficient evidence at the 0.01 level to refute the chief's claim.
Step-by-step explanation:
A local police chief claims that about 51% of all drug related arrests are ever prosecuted
At the null hypothesis, we test if the proportion is of 51%, that is:
\(H_0: p = 0.51\)
At the alternate hypothesis, we test if the proportion is different from 51%, that is:
\(H_1: p \neq 0.51\)
The test statistic is:
\(z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}\)
In which X is the sample mean, \(\mu\) is the value tested at the null hypothesis, \(\sigma\) is the standard deviation and n is the size of the sample.
0.51 is tested at the null hypothesis:
This means that \(\mu = 0.51, \sigma = \sqrt{0.51*0.49}\)
A sample of 900 arrests shows that 47% of the arrests were prosecuted.
This means that \(n = 900, X = 0.47\)
\(z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}\)
\(z = \frac{0.47 - 0.51}{\frac{\sqrt{0.51*0.49}}{\sqrt{900}}}\)
\(z = -2.4\)
P-value of the test:
Probability that the sample proportion differs from 0.51 by at least 0.04, which is P(|z|>2.4), which is 2 multiplied by the p-value of Z = -2.4.
Looking at the z-table, the Z = -2.4 has a p-value of 0.0082.
2*0.0082 = 0.0164.
The p-value of the test is 0.0164 > 0.01, which means that there is not sufficient evidence at the 0.01 level to refute the chief's claim.

Fisrt we can find the similar angles and sides so we know that:
\(\begin{gathered} 2NL=JL \\ NK=\frac{NL}{2} \end{gathered}\)so we can replace like:
\(\begin{gathered} JL=2\cdot13=26 \\ NK=\frac{30}{2}=15 \end{gathered}\)now we can find the distance KL with pithagoras so:
\(KL=\sqrt{15^2+13^2}\)and we operate so:
\(\begin{gathered} KL=\sqrt[]{225+169} \\ KL=\sqrt[]{394} \\ KL=19.8 \end{gathered}\)Now the angle JKM will be equal to the angle MKZ so
\(\angle JKM=41\)Now the angle JML will be:
\(\begin{gathered} \angle JML=\angle JKM+\angle MKZ \\ \angle JML=41+41 \\ \angle JML=82 \end{gathered}\)the angle MLK will be the complement of 82 on a triangle so:
\(\begin{gathered} \angle MLK=180-82 \\ \angle MLK=98 \end{gathered}\)For MNL we know that the segmente MK is perpendicular to JL so the angle is:
\(\angle MNL=90\)and KJL will be halve of the angle MLK so:

Jack has a saving account of value $65,550 at the start. The saving account has an interest rate of 3% that is compounded every six months. How long will it take Jack to have $100,000 in his account?
Answers
Given:
Principal value = $65,550
Rate of interest = 3% compounded every six month
To find:
The taken to have $100,000 in Jack's account.
Solution:
The formula for amount is
\(A=P(1+\dfrac{r}{n})^{nt}\)
where, P is principal, r is rate of interest, n is number of times interest compounded in an year, t is time in number of years.
Interest compounded every six month. It means, interest compounded 2 times in an year.
Substitute A=100000, r=0.03 and n=2 in the above formula.
\(100000=65550(1+\dfrac{0.03}{2})^{2t}\)
\(\dfrac{100000}{65550}=(1+0.015)^{2t}\)
\(1.525553=(1.015)^{2t}\)
Taking log on both sides.
\(\log (1.525553)=\log (1.015)^{2t}\)
\(\log (1.525553)=2t\log (1.015)\)
\(\dfrac{\log (1.525553)}{2\log (1.015)}=t\)
\(t=14.1838928\)
\(t\approx 14.18\)
Therefore, after 14.18 year the amount will reach at $100,000 or we can say that in 15th year the amount will reach at $100,000.

Elena has a

170 when measured in a different unit. Which measurement is in ounces,
and which is in grams?
170
Answers
Measurement of weight 6 is in ounces and the measurement of weight 170 is in grams.
What is measurement?
An object or event's attributes are quantified through measurement so that they can be compared to those of other things or events. Measurement, then, is the process of establishing how big or small a physical quantity is in relation to a fundamental reference quantity of the same kind.
Given:
Elena has a pet parakeet that weighs 6 when measured in one unit and
170 when measured in a different unit.
We have to find the correct units from grams and ounces for these.
We know that, 1 ounce is greater than 1 gram.
1 ounce = 28.3495 grams
Multiply both sides by 6.
6 ounces = 170.097 grams
Approximate the values to the nearest whole number.
6 ounces = 170 grams
Therefore, 6 ounces = 170 grams.
Hence, measurement of weight 6 is in ounces and the measurement of weight 170 is in grams.

The adjacent sides of the parallelogram are (x + 3) and (x + 2). Find the perimeter of the parallelogram.
Answers
Answer:
P = 4x+10
Step-by-step explanation:
So a parallelogram has 2 set of sides which are parallel and equal. So if you're given two adjacent sides, that means you're given a side from each set of sides, which are equal. This means the perimeter is simply: 2(x+3) + 2(x+2). This can be further simplified by distributing the 2 which gives you the equation: 2x+6+2x+4, which further simplifies to 4x+10.

Given, the parabola Y = X² -2 and a line Y = -X. To find the intersection points of this graph we need to compare these equations.
Let's put the value of y in equation 1

How to Interpret a scatterplot?Let us first define the terms in the given options before we analyze the scatterplot.
1) Negative correlation is defined as a relationship between two variables whereby one variable increases while the other decreases, and vice versa.
2) A nonlinear relationship is also referred to as nonlinear association, and it exists when a constant change in the independent variable does not result in a constant change in the dependent variable.
3) An outlier is defined as a data point that differs significantly from other observations.
4) Clusters are small populations that a wider population is divided into.
Now, from the scatter plot, we see that X is isolated from the plotted points which tells us that it differs greatly from the other points and as such it fits the definition of an outlier.

How to determine the domain restrictions for (f/g)(x)?From the question, we have the following parameters that can be used in our computation:
f(x) = x² - 5x - 6
g(x) = x² - 6x
The composite function (f/g)(x) is calculated as
(f/g)(x) = f(x)/g(x)
substitute the known values in the above equation, so, we have the following representation
(f/g)(x) = (x² - 5x - 6 )/(x² - 6x)
For the domain restriction, we have
x² - 6x = 0
