Computer supply store sells types of laser printers each model m cost to store $179 and it sold for 234 were turning a profit of $55 each model and cost to store $139 and it sold for 199 returning a profit of $60. the store expects to sell at least 100 printers each month and must earn a minimum profit of $5775 on those printers. if they must sell at least one of each model, how many of each model should the store order to minimize the cost

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)
