You are testing the null hypothesis that μ = 0 versus the alternative μ > 0 using α = .05. assume σ = 19. suppose x = 5.3 and n = 10. calculate the test statistic and its p-value. repeat assuming the same value of x but with n = 20. do the same for sample sizes of 30, 40, and 50. (round the test statistic to two decimal places. round the p-value to four decimal places.)
a) n = 10: z p-value
b) n = 20: z p-value
c) n = 30: z p-value
d) n = 40: z p-value
e) n = 50: z p-value

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%
