    Every simulation in this module is based on an assumption about the difference between two population proportions. The population proportions affect the mean and the standard error of the differences in sample proportions. The sample size also affects the standard error. The distribution of differences between sample proportions shown below has mean 0.35, and a standard error of about 0.10. Which of the following did we use to generate this sampling distribution? A.Population proportions of 0.85 and 0.65 with samples...

    Small Sample Difference of Means. Company officials were concerned about the length of time a particular drug product retained its potency. A random sample of 10 bottles of the product was from the production line and analyzed for potency (labeled FRESH). A second set of 10 bottles was obtained and stored in a regulated environment for 1 year (labeled STORED). The data are given below. You can safely assume the data are distributed normally. FRESH STORED FRESH STORED 9.8 9.5...
