Can someone tell me how to do this and give me the answer please

This question is incomplete, the complete question is;

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 simplification form of the provided expression is 18.25 option (A) is correct.

It is defined as the combination of constants and variables with mathematical operators.

We have a mathematical expression:

[tex]= \rm \dfrac{7\times8+20(4.5)}{16\times0.5}[/tex]

= (56 + 90)/8

= 146/8

= 18.25

Thus, the simplification form of the provided expression is 18.25 option (A) is correct.

Step-by-step explanation:

Answer:

14

Step-by-step explanation:

Because right angles are 90 degrees, we need to subtract 34 from 90 which gets us 56. That means 56 = 4x, so 56/4 = 14, therefore X = 14.

Hope this helps!

Both angles form a right angle which is 90 degrees.

Angle 2 would equal 90 degrees - angle 1

Angle 2 = 90 -34 = 56

So now we know 4x = 56

To find x divide both sides by 4

X = 14

Answer:

Jose's cost basis for the delivery van = $42,410

Step-by-step explanation:

Cost basis of a fixed asset can be described the original value of an asset for tax purposes which includes the purchase price, shipping, installation, sales tax, and other costs incurred that are related to the purchase of the fixed asset and to make it be in conformity with other assets in its class.

Based on this explanation, Jose's cost basis for the delivery van can be calculated as follows:

Jose's cost basis for the delivery van = Winning bid + Shipping costs + Cost of painting to match other fleet vehicles + Sales tax = $34,750 + $1,470 + $1,590 + $4,600 = $42,410

1. T test for independent means

2. T test for dependent means

3. T test for dependent means

Step-by-step explanation:

In number 1, the two groups are unrelated. The first group has 25 subjects and they're all unemployed. The second group has 24 subjects and their employment status is not stated and might not be the same all through. Also, the first group is receiving a new type of job skills program while the second group is taking the standard job skills program.

- The groups in the experiment are unrelated

- The tests in the research are unrelated

- The purpose of the research is unreasonable - the researcher seeks to measure how well all 49 subjects perform on 'a' job skills test! No comparison between the scores or mean scores of the two groups.

In number 2, the researcher uses the same subjects and also measures the same variable but twice. This is a good example of a study where the t test for dependent means can be taken. Same applies in case 3.

Answer:

The stimulus check impacts society because it helps people or rather encourages people to invest. Not only individuals but also businesses. It also shows how the stimulus check gives more than peoples incomes. Not everyone can get the stimulus check, only tax payers who pay taxes every year and have a public job. This impacts society because not everyone can get the stimulus check, and some people receive lots of money and other people might get just a little. At the end of the day, it all depends on how much taxes you are paying each year and which job you have.

The equation below could be the equation of this parabola is y = -5x².

Option A is the correct answer.

A parabola is an equation of a curve, such that any point on the curve is equidistant from a fixed point called the focus and a fixed line called the directrix of the parabola.

The equation of a parabola:

y = a(x - h)² + k

We have,

Since the parabola vertex is at (0,0) and is open to the left, the equation of the parabola must be of the form:

y = a x², where a is a positive constant.

Now,

The only equation that fits this form is y = -5x².

Thus,

The equation below could be the equation of this parabola is y = -5x².
