Answer:

y = -6

Step-by-step explanation:

Step 1: Define

8x - 9y = -50

x = -13

Step 2: Substitute and solve for <em>y</em>

8(-13) - 9y = -50

-104 - 9y = -50

-9y = 54

y = -6

The National Collegiate Athletic Association (NCAA) requires colleges to report the graduation rate of their athletes. At one la
alukav5142 [94]

Answer:

The 99% confidence interval for the proportion of athletes who graduate is (0.5309, 0.7323).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

For this problem, we have that:

n = 152, \pi = \frac{96}{152} = 0.6316

99% confidence level

So \alpha = 0.01, z is the value of Z that has a pvalue of 1 - \frac{0.01}{2} = 0.995, so Z = 2.575.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6316 - 2.575\sqrt{\frac{0.6316*0.3684}{152}} = 0.5309

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6316 + 2.575\sqrt{\frac{0.6316*0.3684}{152}} = 0.7323

The 99% confidence interval for the proportion of athletes who graduate is (0.5309, 0.7323).
