    Hi guys, I want to know if anybody have any clue about question #8, because I’m littel bit confused with it. Any suggestion professor.
    8. The FDA has decided to measure 8-ounce cans of Hershey Cocoa. The weights of 50 containers are found in the accompanying excel file. The null hypothesis is that the weights average more than 8 oz.
    (a) Use a critical value approach to the t-test at the α = 5% significance level.
    (b) Make a histogram to verify that the weights are approximately normally distributed.
