For numbers 5 to 7: A study was conducted to examine the effect of thermal pollution on the growth of clams. Seven random sample of clams were collected at the intake site without thermal pollution while eight random sample of clams were taken from the discharge site with thermal pollution. The length of each clam (in cm) was measured. It is of interest to test whether there is a difference between the mean length of clams from the sites with and without thermal pollution. 5. Which of the following must be satisfied in order for the parametric test to be valid? I. The clams selected from each site should be taken independently. II. The clam lengths are normally distributed. O A.I only O B. Il only O C. Both I and II O D. Neither I nor II
