In a random sample of six microwave ovens, the mean repair cost was $65.00 and the standard deviation was $12.50. Assume the population is normally distributed and use a t-distribution to construct a 90% confidence interval for the population mean mu. What is the margin of error of mu? Interpret the results. The 90% confidence interval for the population mean mu is ( nothing, nothing). (Round to two decimal places as needed.) The margin of error is nothing. (Round to...
In a random sample of fivefive microwave ovens, the mean repair cost was $75.0075.00 and the standard deviation was $14.0014.00. Assume the population is normally distributed and use a t-distribution to construct a 9090% confidence interval for the population mean muμ. What is the margin of error of muμ? Interpret the results.
In a random sample of five microwave ovens, the mean repair cost was $65.00 and the standard deviation was $14.00. Assume the population is normally distributed and use a t-distribution to construct a 95% confidence interval for the population mean μ. What is the margin of error of μ? Interpret the results.

In a random sample of four mobile devices, the mean repair cost was $60.00 and the standard deviation was $14.00. Assume the population is normally distributed and use a t-distribution to find the margin of error and construct a 90% confidence interval for the population mean. Interpret the results. The 90% confidence interval for the population mean is (DO (Round to two decimal places as needed.) The margin of error is $ (Round to two decimal places as needed.) Interpret...

to estimate the population mean repair cost of microwave ovens in macomb, a random sample of 9 broken microwave ovens was selected and it is found that the sample mean repair cost was $80 with a sample standard deviation of $15. 1) what would be the “critical value” if you want to find a 95% confidence interval for the population mean? 2) what would be the “margin of error” if you want to find a 95% confidence interval for the...
in a random sample of six microwave ovens, the mean repair cost was $60.00 and the standard deviation was $11.00 Round to two decimal places as needed) (Round to two decimal places as needed.) C. It can be said that 99% of microwaves have a repair cost between the bounds of the c interval DOLL
