Critical value and decision rule

Reference no: EM13113514

As a part of a class project, your statistics instructor asks you to weigh a sample of 100 items from a shipment of 500. You are testing the null hypothesis that the mean is greater or equal to 10 lbs. You are given that the standard diviation is 0.05 lb. Accepting H0 is the same as accepting the shipment.

A) using a significance level of alpha =.05 lb, determine the critical value for the applicable test statistics and express the decision rule.

B) What action you should take: 1) if x-bar =10.1 lb, 2) x-bar =9.95 lb, 3) x-bar =9.85 lb
