The president of Doerman Distributors, Inc., believes that 30% of the firm’s orders come from new or first-time customers. A simple random sample of 100 orders will be used to estimate the proportion of new or first-time customers. The results of the sample will be used to verify the president’s claim of p = .30.
Show whether the study meets the success/failure condition.
What is the probability that the sample proportion will be between .20 and .40 (to 4 decimals)?
