Each firm is asked to report the number of new products introduced last year. The survey found that on average these firms introduced 5.68 products with a standard deviation of 8.70. Compute a 98% confidence interval for the new products introduced last year. ---------------------------------- sample mean = 5.68 E = 2.326 = 2.023 ------------ 90% CI: 5.68-2.023 <= u <= 5.68+2.023 =========================================== Cheers, Stan H.
