Zach would like to be 99% confident that the customers are getting at least the amount of chocolate in
ounces (oz) for which they are paying. ShowZach'snull and alternate hypotheses, the significance level
and how he calculates his test statistic, t. Customers expect that the average weight of a kiss is .16 oz
Shall Zach assume that today's chocolate is heavy enough or shall he add kisses to each bag? (Interpret the
hypothesis)
