Exercise 3 Iron Man is checking out a new suit that fires lasers more accurately. If he is aiming for a bullseye, his original suit fires lasers that deviate from their target with a standard deviation of 2mm. Ironman collects 16 measurements from his new suit and finds that it fires lasers with a sample standard deviation of s = 1.6mm. Parts (a) - (b), state the following, showing work where appropriate: null and alternative hypothesis distribution and value of the test statistic p value conclusion (reject or fail to reject ). a. (1 point) Perform a hypothesis test at to test whether there is sufficient evidence to suggest that the new suit is better (more accurate) than the original. b. (1 point) Suppose that Ironman takes 100 measurements and still finds a sample standard deviation of 1.6mm. Perform a hypothesis test at to test whether there is sufficient evidence to suggest that the new suit is better (more accurate) than the original. c. (0.5 points) (2 parts) Perform the hypothesis test in part (b) using
