Question

Transcribed Image Text:8) The Pepsi Challenge is an ongoing marketing campaign run by PepsiCo since 1975 in which participants complete a blind taste test of two sodas (Pepsi and their primary competitor, Coca- Cola) and select their preferred soda. PepsiCo claims that 2 out of every 3 people prefer their brand of cola. A random sample of 140 people is taken, and 85 of them (60.7%) choose Pepsi as their preferred cola. Suppose you wanted to Create a Distribution of Simulated Sample Statistics for One Proportion with 1000 simulated sample statistics representing repetitive sampling from the scenario described above. (a) Explain your steps required to generate a distribution of simulated sample statistics for the scenario above. Your explanation should be written in complete sentences using the appropriate methods, reasoning, and terminology when justifying which values are being used and why. (b) Follow the steps described in (a) to generate a distribution of simulated sample statistics. Select the "Summary Stats" checkbox to display the mean and standard deviation of the distribution. Take a screenshot of the applet displaying the values used and the distribution generated.
