Aboat capsized and sank in a lake. based on an assumption of a mean weight of 149 lb, the boat was rated to carry 60 passengers (so the load limit was 8 comma 940 lb). after the boat sank, the assumed mean weight for similar boats was changed from 149 lb to 175 lb. complete parts a and b below.

a. assume that a similar boat is loaded with 60 passengers, and assume that the weights of people are normally distributed with a mean of 182.5 lb and a standard deviation of 40.4 lb. find the probability that the boat is overloaded because the 60 passengers have a mean weight greater than 149 lb. the probability is

Asample of 200 rom computer chips was selected on each of 30 consecutive days, and the number of nonconforming chips on each day was as follows: the data has been given so that it can be copied into r as a vector. non. conforming = c(10, 15, 21, 19, 34, 16, 5, 24, 8, 21, 32, 14, 14, 19, 18, 20, 12, 23, 10, 19, 20, 18, 13, 26, 33, 14, 12, 21, 12, 27) #construct a p chart by using the following code. you will need to enter your values for pbar, lcl and ucl. pbar = lcl = ucl = plot(non. conforming/200, ylim = c(0,.5)) abline(h = pbar, lty = 2) abline(h = lcl, lty = 3) abline(h = ucl, lty = 3)
