An elevator has a placard stating that the maximum capacity is 3800 lb26 passengers. So, 26 adult male passengers can have a mean weight of up to 3800/26=146pounds. Assume that weights of males are normally distributed with a mean of 188lb and a standard deviation of 26lb. a. Find the probability that 1 randomly selected adult male has a weight

Peak force (N) on the hand was measured just prior to impact and just after impact on a backhand drive for six advanced tennis players. The resulting data, from a paper are given in the accompanying table. Use the signed-rank test to determine if the mean postimpact force is greater than the mean pre- impact force by more than 6.

A factorial experiment was designed to test for any significant differences in the time needed to perform English to foreign language translations with two computerized language translators. Because the type of language translated was also considered a significant factor, translations were made with both systems for three different languages:
