Alpine Research has conducted a survey of online shoppers.Simple random samples of 200 shoppers aged 18-to-25, 100 shoppers aged 26-to-40, and 100 shoppers aged 41-to-65 were selected for the survey.In the 18-to-25 sample, 80 shoppers (40%) expressed concerned about online security.Fifty of the 26-to-40 sample (50%) gave the same response.In the 41-to-65 sample, 66 shoppers (66%) expressed concern about online security. Below is a (partial) table of expected frequencies that you will use to conduct a chi-square test of the null hypothesis that the proportion of shoppers who are concerned about online security is the same in all three populations represented.What is the expected frequency that you should show in the "18-to-25, Concerned" cell of the table?
