At a certain university, the average attendance at basketball games has been 2,825. Due to the dismal showing of the team this year, the attendance for the first 11 games has averaged only 2,515 with a standard deviation of 485. The athletic director claims that the attendance is the same as last year. What is the test value needed to evaluate the claim?

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%
