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

Acable company wants to provide cell phone service for residents on an island. the function for the cost of laying the cable from the island to the mainland is c(x)= 6.500 square root x2+4, where x represents the length of the cable in feet. what are the domain and range of the function? a) domain: all real numbers range: all real numbers greater than or equal to 17,000 b) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 17,000 c) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 13,000 d) domain: all real numbers greater than or equal to 13,000 range: all real numbers greater than or equal to 0
