Freddy is sailing near a buoy. Freddy starts from a point 3 miles EAST and 2a miles NORTH of the buoy. Freddy then sails in a straight line toward a point 4 miles due SOUTH of the buoy. When Freddy reaches the point closet to the buoy on this course, Freddy changes direction and sails due WEST for 10 miles. Freddy sails at a constant speed 7 miles per hour.

For what length of time is Freddy within 3 miles of the buoy?

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)
