To decide whether two different types of steel have the same true average fracture toughness values, n specimens of each type are tested, yielding the following results. Type Sample Average Sample SD 60.4 1.O 60.2 Calculate the P-value for the appropriate two-sample z test, assuming that the data was based on n = 100. (Round your answer to four decimal places.) 0 1527 X Calculate the P-value for the appropriate two-sample z test, assuming that the data was based on n = 400. (Round your answer to four decimal places.) 0.1527 X Is the small P-value for n = 400 indicative of a difference that has practical significance? Would you have been satisfied with just a report of the P-value? Comment briefly. This answer has not been graded yet.
