An electronics manufacturing process has a scheduled mean completion time of minutes. It is claimed that, under new management, the mean completion time, less than minutes. To test this claim, a random sample of new management was taken. , is completion times under The sample had a mean completion time of minutes and a standard deviation of minutes. Assume that the population of completion times under new management is normally distributed. At the completion time, level of significance, can it be concluded that the mean , under new management is less than the scheduled mean? Perform a onetailed test. Then fill in the table below. Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.) The Null Hypo The Alternative Hypo The Type of test statistic The value of the least statistic: Round to the nearest three The critical value at the 0.1 level of significance: round to the nearest three At the 0.1 level, can it be concluded that the mean completion time under new management is less than the scheduled mean? YES or NO
