1. [6] Groups of non-smokers who were not exposed to smoke, and non-smokers who were exposed to secondhand smoke were sampled to test their cotinine levels (ng/mL). Using a 0.05 significance level, test the claim that non-smokers exposed to tobacco smoke have higher mean cotinine levels than non-smokers that are not exposed. Show rejection regions with Exposed to secondhand smoke: n = 40, x = 60.58, s =138.08 labelled critical value(s) Not exposed to secondhand smoke: n = 40, x =16.35, s =62.53 Ho : H1: Critical Value(s): Test Statistic: Must state what test stat is being used (z, t, etc.) the formula being used, and what values are substituted into the formula for full credit. Simply writing a number will not earn credit] P-Value: State the conclusion of the test in the context of the problem (for example, not just "reject null", but what does it mean for this specific problem)
