1. Suppose the alternative hypothesis for a particular test 1 is given by H1: p # 0.25. What is the P-value for this test if test statistic z = 1.85? a. 0.9678 b. 0.0322 C. -0.0644 d. 0.0644 2. A sample of 64 body temperatures has a mean of 98.6 OF. Assume that o is known to be 0.5 F. Use a 0.05 significance level to test the claim that the mean body temperature of the population is equal to 98.5 F, as is commonly believed. What is the value of test statistic for this testing? a. - 1.6 b. 1.6 c. 2.0 d. 2.6 3. The null and alternative hypothesis in symbolic form for the claim: "The mean annual income of employees who took a statistics course is more than $50,000." are: a. Ho: u = 50,000, Hatu 50,000, Ha: > 50,000 C. Ho: H = 50,000, Hail s 50,000 d. Ho: H = 50,000, Ha:u > 50,000 4. You are given the following hypothesis test: Ho: =100 H1: u # 100 The calculated test statistic z = -2.0, and the critical value of z = +1.97. Then, the decision would be to: a. Reject Ho since z
