Suppose there are 1,890; 1,651; 1,792; 1,234; and 2,883 students, respectively, in each of the schools. Use your equation to find the number of students the school district can send to the history competition. Does your answer make sense? Explain.

According to a study conducted in 2015, 18% of shoppers said that they prefer to buy generic instead of name-brand products. suppose that in a recent sample of 1500 shoppers, 315 stated that they prefer to buy generic instead of name-brand products. at a 5% significance level, can you conclude that the proportion of all shoppers who currently prefer to buy generic instead of name-brand products is higher than .18? use both the p-value and the critical-value approaches.
