The formula to calculate the sample size is:
n = Z number * standard deviation/ confidence estimate)^2
The z number for 95% confidence is 1.96
The standard deviation is given as 26 minutes.
The confidence estimate is given as 5 minutes.
The sample size is: (1.96 * 26/5)^2 = 103.87 = 104 shoppers.
The answer is C) 9. The answer is 9 because you have to subtract (5-2) then multiply the answer by 3 which ends up as 9.
