Final grades for Physics 171 have been assigned. The distribution of all the final course grades is shown below:

Letter grades are based on the cumulative course average, which
is weighted according to:
homework (5 problem sets)---40%;
midterm exam---25%; and
the final exam---35%. This cumulative course average is then
converted into a letter grade according to the following
approximate numerical ranges:
A+ (92.5--100); A (87--92.5); A- (81.5--87); B+ (76--81.5); B (70.5--76);
B- (65--70.5); C+ (59.5--65); C (54--59.5); C- (50.5--54); D (47--50.5); F (0--47).
Here is the statistical summary of the distribution of
the cumulative course averages:

mean: 81.14
median: 82.23
standard deviation: 12.4
high: 97.1
low : 47.7

Here are the relevant final exam statistics.
A histogram of the test scores is shown below:

Horizontal axis labels correspond to the midpoint value of a bin,
which is 10 points wide.
