A national survey found that the average cost of repairs after the appearance of a "check engine" light was $1000. A researcher at the Flanagan Motor Club was interested in whether club members (who receive a discount on their repairs) paid less than the national average. A random sample of 35 members was conducted and the results (shown below) analyzed using the .05 significance level. Answer questions #3 and #4 using this output. sample 0 Mean 968.94 1000 Variance 53226.35 Observations 35 df 34 t Stat -0.7964 P(T<=t) one-tail 0.2157 t Critical one-tail 1.6909 P(T<=t) two-tail 0.4313 t Critical two-tail 2.0322 3: The decision rule, using the critical value of t, is: A. Reject Ho if tcalc < -2.032 or tcalc > 2.032. B. Reject Ho if tcalc > 1.691. C. Reject Ho if tcalc < -1.691. D. Reject Ho if tcalc < 1.691
