imferen ) Determine the minimum sample size required to construct a 99% confidence interval for the population mean. Assume the population standard deviation is 6 inch. ) The sample mean is 27.6 inches. With a sample size of 82, a 99% level of confidence, and a population standard deviation of 0.6 inch, does it seem possible at the population mean could be less than 27.7 inches? Explain. lick here to view page 1 of the Standard Normal Table.

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
