Which line most accurately represents the line of best fit for the scatter plot?

A graph shows numbers from 0 to 21 on the x axis at increments of 3 and the numbers 0 to 63 on the y axis at increments of 9. Scatter plot shows ordered pairs 0, 27 and 3, 36 and 5, 37 and 7, 45 and 9, 45 and 9, 54 and 12, 54 and 15, 59 and 18, 63. A line labeled A joins ordered pair 0, 27 and 16, 63. A line labeled B joins ordered pair 0, 27 and 21, 45. A line labeled C joins ordered pair 0, 27 and 21, 31.5. A line labeled D joins ordered pair 0, 27 and 21, 18.

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)
