Inimitably instinctive investigator Sheerluck Hopeless studies Professor Marionasty’s evil organization. According to Sheerluck’s data, Marionasty agents carry either a revolver, an automatic, or no gun at all, and three types of small knives, as indicated in the table below. For the population of Marionasty agents, let X = {Gun Type} and Y = {Knive Type}.

Knives
Guns	Dagger	Stiletto	Switchblade	Totals
None	38	47	15	100
Revolver	17	17	16	50
Automatic	25	16	9	50
Totals	80	80	40	200

a. Do these data provide strong evidence that the proportion of agents who carru switchblades is less than one quarter?

I. Test the hypothesis that less than one quarter of agents carry switchblades

II. Find a comparable confidence interval for the proportion of agents who carry switchblades

III. Compare your interval and test results

b. Use this data to test the hypothesis that there is an association between the types of knives and guns that Marinoasty agents carry.

An investigator plots 1/v as a function of 1/(concentration of substrate) for data collected with and without an inhibitor. The best-fit line of the data collected in the absence of the inhibitor had a slope of 0.12 (arbitrary units of time) and a y-intercept of 0.05 (arbitrary units of time per concentration). The best-fit line of the data collected in the presence of the inhibitor had a slope that was 2.9-times as steep (arbitrary units of time) and a y-intercept...
