Question: A sample of 65 observations is selected from one population. The sample mean is 2.67 and the sample standard deviation is 0.75. A sample of 50 observations is selected from a second population. The sample mean is 2.59 and the sample standard deviation is 0.66. Conduct the following test of hypothesis using the .08 significance level.
- Is this a one—tailed or a two—tailed test?
- State the decision rule.
- Compute the value of the test statistic.
- What is your decision regarding H0?
- What is the p-value? Compute and interpret the p—value.
