(11 points) Participants in a summer workshop on statistics enhanced their study of experimental design by carrying out a series of experiments to measure and compare characteristics of various brands of paper towels. In one experiment a tablespoon of water was placed in the center of a towel stretched over an embroidery hoop. After waiting 30 seconds, a 50-g weight was added to the center of the towel, and then a series of 50-g weights were added every 3 seconds until the towel broke. The response was the total weight on the towel immediately before it broke. The data are shown below. Is there statistically significant evidence of difference among the mean stregths of the towels?

A. Reject Ho. We have significant evidence of differences among the population mean stregths of the towels. B. Fail to reject Ho. We do not have significant evidence of differences among the population mean stregths of the towels.
