Based on historical data, your manager believes that 42% of the company's orders come from first-time customers. a random sample of 85 orders will be used to estimate the proportion of first-time-customers. what is the probability that the sample proportion is between 0.36 and 0.47?

0.9560

Step-by-step explanation:

Given that based on historical data, your manager believes that 42% of the company's orders come from first-time customers

Population proportion p = 0.42

Sample size n = 85

p is Normal with mean = 0.42 and std error =

p is N(0.42, 0.0535)

Or we can say

the probability that the sample proportion is between 0.36 and 0.47
