Dr. B computed descriptive statistics for final grades in her PSY 210 classes at the end of the semester with the following results:
| min = | 52 |
| max = | 99 |
| mean = | 83 |
| median = | 87 |
| standard deviation = | 13 |
If you provided only these descriptive statistics and the fact that
grades were normally distributed (no raw data) to someone
interested in your findings, what would they be able to conclude
about the range of most (roughly 68%) of scores in the class?
Group of answer choices
Most students have a final grade between 52 - 99.
Most students have a final grade between 74 - 100.
Most students have a final grade between 83 - 87
Most students have a final grade between 70 - 96.
Most students have a final grade between 55 - 81.
Homework Answers
From the given information,
As median(87) is near to the maximum value(99),
Hence, we can conclude that maximum data is present at upper side 87-99.
And 68% percent data lies between 1 times Standard deviation below and above mean.
Hence,
The correct answer is.
Most students have a final grade between 70 - 96.
Dear student,
I am waiting for your feedback. I have given my 100% to solve your
queries. If you are satisfied by my given answer. Can you please
like it☺
Thank You!!!

A random sample of 200 BCOM students from recent years was taken
