Question

In a random sample of 60 refrigerators, the mean repair cost was $140.00 and the population standard deviation is $17.30 Construct a 95% confidence interval for the population mean repair cost. Interpret the results. Construct a 95% confidence interval for the population mean repair cost The 95% confidence interval is ( 0 0 (Round to two decimal places as needed ) interpret you results Choose the correct answer below A, with 95% confidence, it can be said that the confidence interval contains the sample mean repair cost O) B. with 95% confidence, it can be said that the confidence interval contains the true mean repair cost c. The confidence interval contains 95% of the mean repair costs. Click to select your answer(s).
