Calculate the mean, standard deviation for the given data.
Make a bar chart to show the distribution of the grades based on Linsly's current grading scale
(A:100-92, B: 91-83, C: 82-74, D: 73-70, and F: 69 and below).
Use the following standard deviation application given in the case study to determine the "new"
range for each grade:
O A: above u+ 1.250
O B: ut1.250
o C: u2.50
O D: ut1.250
O F: below u-1.250
Create a new bar chart to show the new distribution of grades based on a curve.
