Pick one Excel data set (A through F) and investigate whether the data could have come from a normal population using α = .01. Use any test you wish, including a histogram, or MegaStat's Descriptive Statistics > Normal curve goodness of fit test, or MINITAB's Stats > Basic Statistics > Normality Test to obtain a probability plot with the Anderson-Darling statistic. Interpret the p-value from your tests. For larger data sets, only the rst three and last three observations are shown.
