Suppose an experiment is done with criminals released from prison in a certain state where the recidivism rate is 37​%; that​ is, 37​% of criminals return to prison within three years.

One hundred random prisoners are made to attend a​ "boot camp" for two weeks before their​ release, and it is hoped that​ "boot camp" will have a good effect. Suppose 32 of those prisoners return to prison within three years. The null hypothesis is that those attending boot camp have a recidivism rate of  37%.  

a) what is p. sample proportion of successes?

b) what is p0, the hypothetical proportion of success under the null hypothesis

c) what is the value of test statistic  

Answer:

a) sample proportion of successes is 0.32

b) the required value of p₀ is 0.37

c) the required test statistics value is -1.0356

Step-by-step explanation:

Given the data in the question

100 prisoners attend boot camp and 32 of them return to prison within three years

x = 32

n = 100

recidivism rate for the whole state = 37% = 0.37

a)

what is p. sample proportion of successes

p" = x / n

we substitute

p" = 32 / 100

p" = 0.32

Therefore, sample proportion of successes is 0.32

b)  

what is p₀, the hypothetical proportion of success under the null hypothesis

given that;

the population recidivism rate for the whole state is 37%;

p₀ = 37%

p₀ = 0.37

Therefore, the required value of p₀ is 0.37

Null hypothesis             H₀ : p₀ = 0.37

Alternative hypothesis Hₐ : p₀ ≠ 0.37

c)

what is the value of test statistic  

Z = (p" - p₀) / √([tex]\frac{p_0(1-p_0)}{n}[/tex])

so we substitute

= (0.32 - 37) / √([tex]\frac{0.37(1-0.37)}{100}[/tex])

= -0.05 / √0.002331

=  -0.05 / 0.04828

= -1.0356

Therefore, the required test statistics value is -1.0356

The Holbrooks ordered 25 gallons of orange juice and 16 pints of cranberry juice for their resturant. How much juice do they have in all?


Answers = a- 57 gallons b- 29 gallons

c- 216 gallons d- 164 gallons

Answers

Answer:

27gallons

Step-by-step explanation:

First we need to convert 16pints to gallons

Since;

1 pint = 0.125gallons

16 pints = x

Cross multiply

1 * x = 16 * 0.125

x = 2gallons

Since Holbrooks ordered 25 gallons of orange juice and 16 pints of cranberry juice for their resturant, the total juice he has is 25gallons + 2 gallons = 27gallons

m<5 = 110degrees

m<6 = 70degrees

m<7 = 70degrees

m<8 = 110degrees

Step-by-step explanation:

A line has the angles of 180 degrees so if m<1 is 110 then m<2 must be 70degrees. Then m<4 is opposite side of m<1 so it has to be the same number of degrees and the same for m<3 is the opposite side of m<2.

Step-by-step explanation:

Volume of a triangular pyramid = a*(h/3), where a is the area of the base triangle and h is the height from the base to the highest point.

We need to first find a, the area of the bas triangle:

Area of triangle = (1/2)bh, where b is the length of the base and h is the perpendicular height.

a = (1/2)12*4

a = 6*4

a = 24 cm²

Knowing a, we can know find the volume:

Volume = a*(h/3)

= 24*(9/3)

= 24*3

= 72 cm³

You have collected weekly earnings and age data from a sub-sample of 1,744 individualsusing the Current Population Survey in a given year. Given the overall mean of $434.49and a standard deviation of $294.67, construct a 99% confidence interval for averageearnings in the entire population. State the meaning of this interval in words, ratherthan just in numbers. If you constructed a 90% confidence interval instead, would itbe smaller or larger? What is the intuition?

Answers

Answer:

The 99% confidence interval for average weekly earnings in the entire population is between $416.42 and $452.66. This means that we are 99% sure that the true population mean weekly earnings is between these two values.

Due to the smaller margin of error, the confidence interval would be smaller, that is, less likely to contain the true population mean.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.575.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 2.575\frac{294.67}{\sqrt{1744}} = 18.17[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is 434.49 - 18.17 = $416.42

The upper end of the interval is the sample mean added to M. So it is 434.49 + 18.17 = $452.66

The 99% confidence interval for average weekly earnings in the entire population is between $416.42 and $452.66. This means that we are 99% sure that the true population mean weekly earnings is between these two values.

If you constructed a 90% confidence interval instead, would it be smaller or larger? What is the intuition?

For a 90% confidence interval, we would have z = 1.645.

Looking at the margin of error formula, M and z are direct proportional, that is, as z decreases so does M. Due to the smaller margin of error, the confidence interval would be smaller, that is, less likely to contain the true population mean.
