Answer:

Step-by-step explanation:

the points (0,-3) and (2,3)

y2 = 3, y1 = -3, x2 = 2, x1 = 0

Slope m = (y2 - y1)/(x2 - x1)

m = (3 + 3)/(2 - 0)

m = 6/2

m = 3

The equation of line

y - y1 = m(x - x1)

y + 3 = 3(x - 0)

y + 3 = 3x

y = 3x - 3

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).
