18 = The completion time for a production process is believed to be normally distributed with a mean of = 38 minutes and a standard deviation of o 3.6 minutes. A recently appointed production team introduced new efficiencies that they claim make the completion of the process faster. To test this claim, a random sample of n = 13 production shifts were taken and the observed mean completion time was = 34 minutes. a. In testing the production team's claim, select the appropriate alternative hypothesis, H or Ha: < 38 < 34 7 34 > 38 . > 34 + 38 b. At a 0.09, determine the critical value (2 decimal places): = Critical Value= c. The value of the test statistic (2 decimal places) = d. At a 0.09, select the decision/conclusion: = Select an answer Select an answer Reject the null hypothesis. Fail to reject the null hypothesis. evidence to conclude that the new efficiencies introduced make the completion of the process faster
