Part II: One-Population, Average Question.

You can calculate the sample average and sample standard deviation by inputting your data into your calculator and conducting 1-VarStats. Note that you will NOT have the population standard deviation. Instead, you will use the sample standard deviation. Because you do not have the population standard deviation for an average problem, you will use the t distribution

PROBLEM DATA:
