A research laboratory is studying the effect of temperature on the compressive strength of a certain metal. Five metal specimens are treated at each of four temperatures, and the compressive strength of each specimen is measured. The results are shown next: Use a 10% significance level. (1) Select the right hypothesis to test the mean strength differs with temperature; a Hip UMMM, VS H : At least two meana differ b.H : N = = =u VS H : P X , zuzu d. H :p = =p =p vs H : At least two means differ (2) Consider the following Minitab ANOVA output. Fill in the missing values. Round your answer to 2 decimal places. Analysis of Variance Source DF Adj SS Adj MS F-Value F-Critical Temp 3 202 . 44 Error 16 18 .08 1 . 13 Total 19 220 .52 (3) Can you conclude that the mean strength differs with temperature? Select one right answer. a. The test statistic (F-value) F-critical, reject HO. Mean strength differs with temperature. d. The test statistic (F-value) > F-critical, do not reject HO. Mean strenght does not differ with temperature
