23?
A. 2.074
B. 1.717
C. 2.069

2) The normally distributed AAA battery life is stated to be 350 days when used in
a clock radio. The Big Charge Battery Company has recently modified the AAA
batteries so as to extent their life. The owner of the company wanted to know if the
improved batteries really did last significantly longer. A sample of 100 of the
improved batteries was tested. It was discovered that the mean life was 362 days
and the sample standard deviation was 10 days. The research department decided
to conduct the test at the 0.05 level of significance whether the modification actually
increased the life of the AAA battery. What was their decision rule?
A. Reject the null hypothesis if computed z is less than 1.96.
B. Do not reject the null hypothesis if computed z is 1.65 or greater.
C. Do not reject the null hypothesis if the z test statistics is 1.96 or greater.
D. Reject the null hypothesis if computed z is 1.96 or greater.

level = 0.01?

conducted by the state, indicated that 60 percent of those families looking to buy a
home in Arizona desired to buy a condominium. K & S Construction wanted to
know if this figure applied to Phoenix. They collected a sample of 500 individuals
that had expressed plans to buy a new home. The z-distribution was selected for
this proportion test. The null hypothesis is p = 0.60 and the alternate is p ≠ 0.60.
The significant level selected was .05. From the sample of 500, it was determined
that 290 wanted to buy a condominium. What decision should be made regarding
the null hypothesis?
A. The test level of .05 is not acceptable
