Four laboratories are being used to perform chemical analysis. Samples of the same material are sent to the laboratories for analysis as part of the study to determine whether or not they give, on the average, the same results. The analytical results for the 4 laboratories are as follows: Laboratory A B D 58.7 62.7 55.9 60.7 61.4 64.5 56.1 60.3 60.9 63.1 57.3 60.9 59.2 60.3 59.1 55.2 61.4 58.2 58.1 62.3 Perform the ANOVA at the 0.05 level of significance and give conclusions concerning the laboratories. The conclusion is a. There is no significant relationship among the average number of chemicals produced by the four laboratories. b. The average number of chemicals produced by the four laboratories are the same. c. There is a significant relationship among the average number of chemicals produced by the four laboratories. d. At least two of average number of chemicals produced by the four laboratories are significantly. A
