Two different types of alloy, A and B, have been used to manufacture experimental specimens of a small tension link to be used in a certain engineering application. The ultimate strength (ksi) of each specimen was determined, and the results are summarized in the accompanying frequency distribution. A 26-<30 7 30-<34 13 34-<38 17 38-<42 8 B 6 11 21 12 m = 45 n = 50 USE SALT Compute a 95% CI for the difference between the true proportions of all specimens of alloys A and B that have an ultimate strength of at least 34 ksi. (Estimate the interval as PA PB. Round your answers to four decimal places.) ksi
