Note that the 5% critical value for the t distribution with df larger than 120 is between 1.658 and 1.645. The t statistic on experience 2.4 in the regression (with n=526) of lwage on education, experience and tenure. Therefore if I was doing 5% level of significance test of the null that the population coefficient on experience vs the alternative that the coefficient is positive then what would be my decision?

a. Reject the null hypothesis

b. Accept the null hypothesis c

c. Not sure since we do not know the exact critical value

The Student's t distribution table gives critical values for the Student's t distribution. Use an appropriate d.f. as the row header. For a right-tailed test, the column header is the value of α found in the one-tail area row. For a left-tailed test, the column header is the value of α found in the one-tail area row, but you must change the sign of the critical value t to −t. For a two-tailed test, the column header is the value...

In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value by a small amount and therefore produce a slightly more "conservative" answer.
