    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.
    H0: _1 _ _2
    H1: _1 > _2
    a. Is this a one-tailed or a two-tailed test?
    b. State the decision rule.
    c. Compute the value of the test statistic.
    d. What is your decision regarding H0?
    e. What is the p-value?
    Note: Use the five-step hypothesis testing procedure to solve the following exercises
