1b) The professor would like the middle 40 percent of students to be assignee a grade of "C". . 1b)i. (2 POINTS) Let S be the cutoff score between a D and C grade (so S is less than the mean grade). Let T be the cutoff score between a C and a B grade (so Tis greater than 53 points) Let x be the score of a randomly selected student. Write down in mathematical (probabiity) notation, the chance that xis a grade C (that is, x is between Cand T). This probability equals 40% or 0.40. I got you started below. . 0.40 -PL 1bil. (4 POINTS) Draw a fully labeled normal curve picture representing the values S and T. This includes labeling the central area, as well as the area to the left of Sand the area to the right of T, as well as labeleing the center of the curve with the mean, and label which normal curve was drawn. 15. (4 POINTS) Rounded to 1 decimal place, 5 - 49.9 points and T-56.1 points. Tell me the exact calculator or Google Sheet notation you would use to find these values TH
