Score: 0 of 1 point In a random sample of six mobile devices, the mean repair cost was $65.00 and the standard deviation was $11.50. Assume the population is normally distributed and use a t-distribution to and construct a 99% confidence interval for the population mean. Interpret the results. The 99% confidence interval for the population mean u is ( ). (Round to two decimal places as needed.) The margin of error is $ (Round to two decimal places as needed.) Interpret the results. Choose the correct answer below. O A. It can be said that 99% of mobile devices have a repair cost between the bounds of the confidence interval. O B. With 99% confidence, it can be said that the repair cost is between the bounds of the confidence interval. OC. With 99% confidence, it can be said that the population mean repair cost is between the bounds of the confidence interval. O D. If a large sample of mobile devices are taken approximately 99% of them will have repair costs between the bounds of the confidence interval.

Suppose you take a random sample of n = 80 Douglas College students and ask each student their age. You find that the mean age of students in this sample is X = 22.0375 years and the sample standard deviation is s = 3.2014 years. Fill in the blanks (rounding to four decimal places): The 95% confidence interval for the mean age μ of all Douglas College students is from ______ years to ______ years.
Tina catches a 14-pound bass. She does not know the population mean or standard deviation. So she takes a sample of five friends and they say the last bass they caught was 9, 12, 13, 10, and 10 pounds. Find the t and calculate a 95% (α = .05) confidence interval.
