In an experiment, a fair six-sided number cube, numbered 1 through 6, was rolled 2 times to determine the probability of rolling an even number in the first roll and a number greater than 4 in the second roll. The trial was repeated 10 times. The data from the experiment is shown below. What is the experimental probability of rolling an even number in the first roll and a number greater than 4 in the second roll?

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.
