The Population Mean for daily high temperatures in Hawaii for the month of January is 80 degrees; however, the Population Standard Deviation is Unknown. A researcher tests whether mean January temperatures in Hawaii have been significantly higher over the last 9 years. The researcher calculates the mean temperature for the month of January for the years 2012 through 2020. The Sample Mean temperature for this 9-year period (sample) is 87 degrees. The researcher wants to maximize the Power of the...

The high temperatures (in degrees Fahrenheit) of a random sample of 7 small towns are: 98.4 99.5 99.1 97.3 99.6 97.6 97.1 Assume high temperatures are normally distributed. Based on this data, find the 99% confidence interval of the mean high temperature of towns. Enter your answer as an open-interval (i.e., parentheses) accurate to two decimal places (because the sample data are reported accurate to one decimal place). 99% C.I. = Answer should be obtained without any preliminary rounding. However,...
