Six canoes are made by hand from the same mold, 3 in kevlar with weights 51, 55, and 53 pounds, and 3 in fiberglass with weights 63, 54, and 61 pounds. Suppose the weight distributions for kevlar and fiberglass have the same shape. Use the Wilcoxon rank sum test to decide whether the data are strong evidence of a shift between the two distributions. The null hypothesis is Ho: The two population distributions are identical. Which alternate hypothesis HA is best? The kevlar population distribution is shifted left relative to the fiberglass population distribution The kevlar population distribution is shifted right relative to the fiberglass population distribution The kevlar population distribution is shifted relative to the fiberglass population distribution
