Suppose a random sample of 30 customers is taken to test a company’s claim that 85% of customers are satisfied with their dog food. Assume trials are independent. What is the probability 25 customers are satisfied?
Homework Answers
This is binomial distribution with n = 30 and p = 0.85
(rounded to 4 decimal places)
Hence, 0.1861 is the probability that 25 customers are satisfied.
Please comment if any doubt. Thank you.

A tourism company claims that 50% of its customers are satisfied with the service and prices. a. If this claim is true, what is the probability that in a random sample of 600 customers less than 45% are satisfied? b. Suppose that in a random sample of 600 customers, 270 express satisfaction with the company. What does this tell you about the company’s claim?

An online retailer claims the proportion of on-time deliveries is 85%. To test this claim, a random sample of deliveries are monitored and checked for on-time delivery status. Assume that the test statistic for this hypothesis test is 1.99. Since this is a two tailed hypothesis test, assume that the critical values for this hypothesis test are −1.96 and 1.96. Come to a decision for the hypothesis test and interpret your results with respect to the original claim. Select the...
