QUESTION There are 1000 employees in a firm, 45% are female. A sample of 25 employees is selected randomly. What is the probability that the sample proportion of females is greater than 32%?
Homework Answers
Question 1
Proportion of females, p = 0.51
Sample size, n = 33
Standard error of the sample Proportion = √(p(1-p)/n)
= √(0.51*(1-0.51)/33)
= 0.087
