You select a random sample of 105 fir trees and find that 33 of them have the fungus. A sample of 69 pine trees shows that 9 of them have the fungus. Construct a 99% confidence interval for the difference between the population proportions. Give the standard critical value and round your confidence bounds to two decimal places.a) The critical value is: 2.575b) The confidence interval is: ≤p1−p2≤
