1) Hypothesis Testing
A. For the statement: The mean amount of Pepsi in cans is at least 12 oz. Express the null hypothesis and the alternative hypothesis in symbolic form.
B. Find the z value for the following : The claim is u(mu) =12, and the sample statistics include n =36, xbar = 12.19 and s = .11
C. Determine whether the null hypothesis should be rejected, or whether there is insufficient evidence to reject the null hypothesis
2) When telephone solicitors call from the national magazine company, 18% of the people who answer stay on the line for more than a minute. If 800 people are called in one day, find the probability that at least 150 stay on the line for more than one minute.© BrainMass Inc. brainmass.com June 20, 2018, 1:09 pm ad1c9bdddf
