d.    (6 pts.) A simple random sample of 8 values is drawn from a normally distributed random variable with unknown standard deviation for a hypothesis test of the variable’s mean. find the P-value associated with the following test statistics for the tests described.
a.    The test is right-tailed, and the test statistic is t = 1.895

b.    The test is left-tailed, and the test statistic is t = - 0.711

c.    The test is two-tailed, and the test statistic is t = - 2.998
