A P-value of 0.12 is calculated on a hypothesis test with a significance level set at 0.01. Which of the following is the correct conclusion for the test?
a. Claim the null hypothesis is true
b. Fail to reject the null hypothesis
c. Reject the null hypothesis
d. Claim the alternative hypothesis is true
Which of the following are not requirements for using the t-distribution for a hypothesis test concerning μ? (More than one answer may be correct.)
a. Sample is a simple random sample
b. Sample size must be larger than 30
c. Population must be normally distributed
d. The population standard deviation must be known
Which of the following is true with regard to a P-value? (More than one answer may be correct.)
a. The P-value is generated under the assumption that the null hypothesis is false.
b. The P- value may never be negative.
c. As the P-Value approaches 0 is it is less likely the null hypothesis will be rejected.
d. In a left-tailed test if the P-Value is 0, the test statistic equals the population value as stated in the null hypothesis.

    p-value Approach: The p-value is the smallest significance level at which the null hypothesis is rejected. While using the normal distribution, suppose, z = Zobserved is the test statistic value for testing the hypothesis about a population mean. This test statistic value is usually negative for a left-tailed test and is usually positive for a right-tailed test. The p-value is obtained with the help of the Standard Normal Distribution Table (Table IV). 1. For a left-tailed test, p-value = P(z<...

C we would also reject the null hypothesis if the significance level had been 0.01 instead of 0.05. D All answer options are correct.
