Question 1073873: The distribution of grades in a large statistics course
is as follows:
Grade: A // B // C // D // F
Probability: 0.2 // 0.3 // 0.3 // 0.1 // 0.1
To calculate student grade point averages, grades are expressed in a numerical
scale with A = 4, B = 3, and so on down to F = 0.
(a) Find the expected value. This is the average grade in this course.
- The expected value is 2.2
(b) Explain how to simulate choosing students at random and recording their
grades. Simulate 50 students and find the mean of their 50 grades. Compare
this estimate of the expected value with the exact expected value from (a). (The
law of large numbers says that the estimate will be very accurate if we simulate
a very large number of students.)
Need help with part b! Thanks
Answer by Fombitz(32388) (Show Source): You can put this solution on YOUR website!
You can generate random numbers using EXCEL.
You can use the function RANDBETWEEN and VLOOKUP to generate appropriate ranged random numbers.
Look up "creating discrete probability distributions with EXCEL" on any search engine.
There are even Youtube videos.
Good luck!
