Suppose that a sample of T=36 recent college graduates is used estimate the model y, = B+e,where y, is the hourly wage rate. We have: y = $22.2,o² = 36(a) Test whether the mean wage for recent college graduates is $20/hour at a = 1% (Be sure tostate the null and the alternative hypotheses, the test statistics, their distribution and d.f., andyour decision for this test).(b) Construct a 90% confidence interval estimation for B.

Given: Sample size (n) = 36 y¯=22.2σ2=36yt=β+etμy=20α=0.01 et ~ N (0, σ2=36)

nere y, is the hourly wage rate. We have: y = $22.2, o? = 36 (a) Test whether the mean wage for recent college graduates is $20/hour at a = 1% (Be sure t state the null and the alternative hypotheses, the test statistics, their distribution and d.f., an your decision for this test). (b) Construct a 90% confidence interval estimation for B.
