You are the incoming inspector for potato chips - you are to ensure that each bag has 16 ounces or more in it. You want your testing to be at the level of significance of 0.05. You pull a sample of 49 bags of chips from a recent truckload. Your sample statistics are:

x-bar (the sample mean) = 15.9 ounces

s ( the sample standard deviation) = 0.35 ounces

(a) what is the null and alternative hypothesis

(b) one or two tailed test ??

(d) what is the calculated z value ??
