Selecting appropriate distributions for constructing confidence.
You would like to construct a 95% confidence Interval to estimate today's population mean temperature, so you make a series of measurements (a random
sample) throughout the day. The mean of these measurements is 58 degrees Fahrenheit, and their standard deviation is 3 degrees Fahrenheit.
(a) What is the best point estimate, based on the sample, to use for the population mean?
I degrees
(b) For each of the following sampling scenarlos, determine which distribution should be used to calculate the critical value for the
95% confidence Interval for the population mean.
(In the table, Z refers to a standard normal distribution, and t refers to atdistribution.)
