In a random sample of  style=”color:rgb(0,0,0);”>five microwave​ ovens, the mean repair cost was ​$75.00 and the standard deviation was ​$14. Assume the population is normally distributed and use a​ t-distribution to construct a 90​% confidence interval for the population mean μ. What is the margin of error of μ​? The 90​% confidence interval for the population mean μ is ​
Choose the correct answer below. A.It can be said that 90​% of microwaves have a repair cost between the bounds of the confidence interval.B.With 90​% ​confidence, it can be said that the repair cost is between the bounds of the confidence interval.C.If a large sample of microwaves are taken approximately 90​% of them will have repair costs between the bounds of the confidence interval.D.With 90​% ​confidence, it can be said that the population mean repair cost is between the bounds of the confidence interval.
