A “fun-size” Snickers bar is supposed to weigh 20 grams. Assume that the weights of

Snickers fun-size bars are normally distributed. A random sample of 9 bars is obtained

and their weights in grams are:
20.6 19.7 19.6 20.4 20.7 19.9 21.0 20.3 20.1
Test the hypothesis that the average weight fun-size Snickers bars is actually greater

than 20 grams.
Write out all 4 steps of the 4-step process. You may use Statcrunch to find the test

statistic (handwritten calculation of z, t, or p-value is NOT required), but copy all relevant

numbers needed to make your conclusion below.
