Question

(2) In one study of smokers who tried to quit smoking with nicotine patch therapy tried to quit smoking with nicotine patch therapy, 45 were smoking one year after the treatment and 36 e not smoking one war after the treatment. Use a significance level to test the claim that amane smokers who try to quit with nicotine patch therapy, the majority are smoking a year after the treatment. What do these results suggest about the end tiveness of nicotine patch therapy for those trying to quit smoking? 57 Step A. Identify the given information using proper mathematical notations: (i) The sample site (ii) The sample proportion () The significance level (vi) Are they (v) g = (iv) np = Step B. Formulate the null and alternative hypothesis: Ho Step C. Determine: (1) whither a 2-test or a t-test should be used: (ii) tell whether this is a left, right or two-tailed test (iii) Find the critical value using the significance level o 5%: (iv) and the rejection region using a bell-shaped diagram: Step D. Assuming that the null hypothesis is true, determine the means and standard deviation of the sample statistic p Step E. Find the values of the test statistic z; and the P-value Step F. Make your conclusion and then answer the question in plain English: Step G. What type of error is possible? Interpret the meaning of such an error:

According to the ginen irformation, - Total sample n=45+36=81 (1) Samble size n= 8/ (F) Semple frusportion f= hs = 0.56 (of smokers) (ii) Significance lewe d = 0.03 (please cheek, it must be 0.05) (IV np = 8140.56= 48:36 = 45 (V) nq = (1-) - 81(1-0-56) = 35.64 = 36 (vi) yer they are 7,5

Step B - Before moving step B, we are taking majorty as - greater than 50% which can be 55%, 20% etc. Ho: P = 0.52 ( 52% > 50% showing majorly) N : P 70:52 Stupcimas np. nq 75 and ny 30, 2 test (1) Right failed siid Gitical value (+ 1.645 (iv) Rejuction negin 0.65 1.645
