A manufacturer of a new nicotine nasal spray claims that their product has a 30% success rate for smoking cessation. In a clinical study involving 150 smokers, 93 of them quit smoking. Test the hypothesis that the success rate claimed by the manufacturer is valid at the 5% level of significance. 5) Which of the following is true for this problem? Ho: p = 0.30 H,: p > 0.30 (one-sided) Ho: p = 0.30 H,: p + 0.30 (two-sided) Ho: p = 0.70 H,: p + 0.70 (two-sided) Ho: p = 0.70 H,: p> 0.70 (one-sided) 6) Under what condition should you reject the null hypothesis? а. b. %3D C. |리 > Zo05(1) |Z| < Zo.05(2) |Z| > Zo.o5(2) d. IZ| < Zo.05(1) 7) What is your conclusion? Reject HO b. Do Not Reject HO а. b. C. а.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
