One of a treatment (a nutritionally enriched environment) or a control group (no nutritional enrichment) are randomly selected to be applied to each of a number of otherwise similar seeds. After a fixed time, the resulting seedling plants are dried and then weighed. Armed with the results of this study, which tool would you use to evaluate the claim that 25% of the treatment plants will have a weight greater than 5 grams? a. Binomial exact test b. Chi squared test for goodness of fit c. Chi squared test for independence d. Fisher's exact test e. T-test for an unknown mean t-test for a difference in means f. F-test for equality of group means
