Can you help me answer the question by using my material that shows on pictures? Can you show the calculation for finding the answer?

157-1 exercise2 The Magical Toy company manufactures a line of wrestling action figures. Maude Troston, the head of the doll department, must make the final decision regarding which of two models, Karnivorous Kong or Peter the Pipsqueak," should be discontinued. 157-2 exercise2 Magical Toy ships crates containing equal numbers of Pipsqueaks and Kongs to retail outlets. 45 randomly selected toy stores have sold an average of 78% of all Pipsqueaks delivered to them. 48 other stores have sold an average of 84% of their Kongs. Significance Level Null Hypothesis Alternative Hypothesis Pipsqueak Kong Sample Size (n) 42 48 Sample Proportion (P) 0.78 0.84 157-3 exercise2 Question At a significance level of 0.05, do the data indicate that one action figure sells better than the other? A. Yes. 6. ONo. Significance Level 0.05 Null Hypothesis Alternative Hypothesis Pipsqueak Kong Sample Size (n) 45 48 Sample Proportion ( P) 0.78 0.84 157-4 exercise2 Maude wants to know if one figure sells better, but doesn't have a preconception about which figure might be flying off the shelves. Thus you use a two-sided test, and your alternative hypothesis simply states that there is a difference between the two population proportions, Significance Level 0.05 Null Hypothesis PPID = Pkong Alternative Hypothesis PPip * Pkong Pipsqueak Kong Sample Size (n) 48 Sample Proportion (p) 0.78 0.84 157-5 exercise2 Using the appropriate formula and the data, you find the z-value for the difference between the sample proportions. The z-value is -0.738. Z = ( PPip" Pkang ) - (Ppip' Plane) Pop (1 - Pro) + Prong (1 - Phone)157-5 exercise2 Using the appropriate formula and the data, you find the z-value for the difference between the sample proportions. The z-value is -0.738. Z : ( Ppip" Pkong ) - (Ppip" Plans) Pop (1 - Pop) - Prone (1 - Prone) 12 Pp 11 Kors (0.78 - 0.84) - (0) = -0.738 (0.78)(0.22) (0.84)(0.16) 45 48 Significance Level 0.05 Null Hypothesis PPip = PKong Alternative Hypothesis Ppip * Pkong Pipsqueak Kong Sample Size (n 45 48 Sample Proportion (p) 0.78 0.84 157-6 exercise2 A z-value of -0.738 corresponds to a left tail probability of 0.2303. You double this to find the p-value for the two-sided test. The p-value is 0.4606 Significance Level 0.05 Null Hypothesis PPip = PKong Alternative Hypothesis Ppip # Pkong Pipsqueak Kong Sample Size (n) 45 48 Sample Proportion (p) 0.78 0.84 p-value = 0.4606 0.2303 0.2303 .0.738 +0.738 157-7 exercise2 The p-value is greater than the significance level. Therefore, you can't reject the hypothesis, The data do not show conclusively that one action figure sells better than the other.
