.The CEO of a company believes that 20% of the firm's orders come from first-time customers. Let p denote this proportion for the population of all customers. Assume that there is an infinite number of orders. A random sample of 100 orders will be used to estimate the proportion of first-time customers. Assume the CEO is correct and p = 0.20. Answer questions 1-2.

1.What is the standard deviation of the sample proportion?

0.3

0.02

0.21

0.04

2.What is the probability that the sample proportion will be less than 0.25?

0.55

0.45

0.894

0.106
