A research intern would like to estimate, with 90% confidence, the true proportion of employees who hold two jobs. No preliminary estimate is available. The researcher wants the estimate to be within 3% of the population mean. The research intern has a table to use: z0.10 z0.05 z0.025 z0.01 z0.005
1.282 1.645 1.960 2.326 2.576
They complete the calculation for the minimum sample size as follows:
n = 1.645^2(0.5)(0.5)/3^2
= 0.169
Which the intern then rounds up to 1. Which value in the calculation is incorrect?

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%

the answer is c. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

the best estimate is 3 because   8 can only go into 24 3 times
