Question: Problem 3.3

Because of the way aluminum cans are stacked when they are shipped, they need to be able to bear a minimum of 200 pounds before collapsing. Column B on the spreadsheet contains the weight at which a sample of 150 cans taken from the Birmingham plant collapsed.

a) Using alpha = .05, conduct a one-tailed t test of the hypothesis that average weight bearing capacity is greater than 200 pounds.

b) What is the p value associated with your sample mean weight?

c) What conclusions can you draw from these results?
