Question
The 95% confidence interval for the population mean 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.
A. If a large sample of microwaves are taken approximately 95% of them will have repair costs between the bounds of the confidence interval.
B.With 95% confidence, it can be said that the population mean repair cost is between the bounds of the confidence interval.
C.It can be said that 95% of microwaves have a repair cost between the bounds of the confidence interval.
D.With 95% confidence, it can be said that the repair cost is between the bounds of the confidence interval.
In a random sample of six microwave ovens, the mean repair cost was $80.00 and the standard deviation was $12.00. Assume the population is normally distributed and use a t-distribution to construct a 95% confidence interval for the population mean What is the margin of error of H? Interpret the results.Explanation / Answer
The correct answer is C. The confidence intervals are given for the population from the sample and C correctly identified this
