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 value of the test statistic? b. What range of values is the p-value in? c.At the 8% significance level, can the null hypothesis be rejected?
