To estimate the mean score μ of those who took the medical college admission test on your campus, you will obtain the scores of an srs of students. from published information, you know that the scores are approximately normal with standard deviation about 6.6. how large an srs must you take to reduce the standard deviation of the sample mean score to 1? (round your answer up to the next whole number.)

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.
