For students who first enrolled in two year public institutions in a recent semester, the proportion who earned a bachelor's degree within six years was 0.389. The president of a certain college believes that the proportion of students who enroll in her institution have a higher completion rate.
(a)
Determine the null and alternative hypotheses.
(b)
Explain what it would mean to make a Type I error.
(c)
Explain what it would mean to make a Type II error.

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

answer:

24pi or letter c

answer: the center is the median and/or mean of the data. the spread is the range of the data. and, the shape describes the type of graph. the four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform. good luck

step-by-step explanation:

correct answer was 0.5
