Check my work A sample of 65 observations is selected from one population with a population standard deviation of 0.75. The sample mean is 2.67. A sample of 50 observations is selected from a second population with a population standard deviation of 0.66. The sample mean is 2.59. Conduct the following test of hypothesis using the 0.08 significance level. Ho : MISH2 H1 : H1 > H2 a. Is this a one-tailed or a two-tailed test? One-tailed test O Two-tailed test b. State the decision rule. (Negative values should be indicated by a minus sign. Round your answer to 2 decimal places.) The decision rule is to reject HO if z is greater than 0.08
