The National Center for Education Statistics reports that the proportion of college freshmen who return to the same school for their sophomore year is 0.69. Suppose we select a random sample of 440 freshmen from across the nation. Question 1. What is the expected value of the sampling distribution model for the proportion of 440 freshmen that will return to the same school for their sophomore year

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.

95.03 is the answer. hope this !

the answer is 21%.
