You are conducting a hypothesis test where the null hypothesis is that mu is greater than or equal to 98.6. Your test will be at the 0.05 significance level. You take a sample of 50 people (a large sample), and find that the sample average is 101, and the standard deviation is 2. What is/are the critical values for this test? Group of answer choices a 1.64 b -1.64 c -1.64 and 1.64 d -1.96
State the null and alternate hypothesis. Will you use a left tail, right tail or 2 tailed test? Identify the sampling distribution to be used: standard normal, Student’s t or chi squared.

You are deciding whether to employ a z procedure or a t procedure to test hypotheses about the mean of a population using a significance level of 0.05 for a sample size of 50. Which of the following statements is correct? Question 17 options: You should not use the t procedure, because the population does not have a Normal distribution. You may use the z procedure, but only if you use the sample standard deviation. You may not use the z procedure because you know the population standard deviation. You should use the t procedure, provided you do not know the population standard deviation.
