A researcher is testing a new product to combat pests in forests. In a planting area, 66 trees were treated with product A, and 270 trees received product B. Among those treated with product A, 7 had some type of problem and, among those treated with product B, 49 developed some kind of problem. kind of problem. To check if the rate of problems was the same between the trees that received product A and B, perform an adequate hypothesis test considering a significance level of α=0.08 a. What is the distribution of the test statistic? b.What kind of alternative hypothesis? c. What is the test's critical value (the value that defines the critical region), on the scale of the test statistic? (If the test is bilateral, enter only one of the values.) .
