The National Assessment of Educational Progress (NAEP) gives a math assessment every year to 12th graders in the U.S. On the mat
amid [387]

Answer:

The correct answer is option 2.

Step-by-step explanation:

In this case we need to test whether young men nationwide have a mean score below 275 in the National Assessment of Educational Progress math assessment.

The hypothesis is defined as follows:

<em>H₀</em>: <em>μ</em> = 275 vs. <em>Hₐ</em>: <em>μ</em> < 275

The significance level of the test is <em>α</em> = 0.05.

The <em>p</em>-value of the test is computed as, <em>p</em>-value = 0.20.

Decision rule:

A small <em>p</em>-value (typically ≤ 0.05) specifies solid proof against the null hypothesis (<em>H₀</em>), so you discard the null hypothesis.

A large <em>p</em>-value (> 0.05) specifies fragile proof against the null hypothesis, so you fail to discard the null hypothesis.

<em>p</em>-value = 0.20 > <em>α</em> = 0.05.

The null hypothesis was failed to rejected at 5% level of significance.

Thus, it can be concluded that there is not enough evidence to conclude that the mean score is less than 275 for young men nationwide.

Thus, the correct answer is option 2.

Crime and Punishment: In a study of pleas and prison sentences, it is found that 45% of the subjects studied were sent to prison
Gala2k [10]

Answer:

(a) The probability of getting someone who was not sent to prison is 0.55.

(b) If a study subject is randomly selected and it is then found that the subject entered a guilty plea, the probability that this person was not sent to prison is 0.63.

Step-by-step explanation:

We are given that in a study of pleas and prison sentences, it is found that 45% of the subjects studied were sent to prison. Among those sent to prison, 40% chose to plead guilty. Among those not sent to prison, 55% chose to plead guilty.

Let the probability that subjects studied were sent to prison = P(A) = 0.45

Let G = event that subject chose to plead guilty

So, the probability that the subjects chose to plead guilty given that they were sent to prison = P(G/A) = 0.40

and the probability that the subjects chose to plead guilty given that they were not sent to prison = P(G/A') = 0.55

(a) The probability of getting someone who was not sent to prison = 1 - Probability of getting someone who was sent to prison

      P(A') = 1 - P(A)

               = 1 - 0.45 = 0.55

(b) If a study subject is randomly selected and it is then found that the subject entered a guilty plea, the probability that this person was not sent to prison is given by = P(A'/G)

We will use Bayes' Theorem here to calculate the above probability;

    P(A'/G) =  \frac{P(A') \times P(G/A')}{P(A') \times P(G/A') +P(A) \times P(G/A)}      

                 =  \frac{0.55 \times 0.55}{0.55\times 0.55 +0.45 \times 0.40}

                 =  \frac{0.3025}{0.4825}

                 =  <u>0.63</u>

A line with a slope of 1 passes through the point (4,2). What is its equation in
dsp73

Answer:

y = x -2

Step-by-step explanation:

Equation of the line : y =mx + b

m = 1

y = 1x + b

Plugin x = 4 and y =2 in this equation

2 = 1*4 + b

2 -4 = b

b = -2

Equation: y = x  - 2
