There will be a section of true/false, yes/no, multiple choice type questions similar to what we had on test 1 and 2 that will cover the entire course. For examples of these types of questions review the study guides for test 1 and 2. Hypothesis Testing:1) Consumer Reports wants to test the claim that the mean amount spent on Black Friday is $450.65. A random sample of 75 Black Friday shoppers finds a mean of $323.45 with a standard deviation of $23.86. Assume a 0.05 level of significance and that the population is normally distributed.a)State the null and alternate hypothesis.
b)What distribution should be used to test the claim?
c)Looking at the minitab output below, what is the test statistic and p-value?
T P
0.000
d)Based on the p-value, should you reject or fail to reject the null hypothesis?
e)Restate the decision in terms of the claim.
2) Consumer Reports wants to test the claim that the mean amount spent on Black Friday less than $450.65. A random sample of 75 Black Friday shoppers finds a mean of $323.45 with a standard deviation of $23.86. Assume a 0.05 level of significance and that the population is normally distributed.a)State the null and alternate hypothesis.

3) Consumer Reports wants to test the claim that the mean amount spent on Black Friday is no more than $450.65. A random sample of 75 Black Friday shoppers finds a mean of $323.45 with a standard deviation of $23.86. Assume a 0.05 level ofsignificance and that the population is normally distributed.a)State the null and alternate hypothesis.
