b. Is this a valid probability distribution? Justify briefly. c. What is the expected value of the number of students found to be in violation of academic integrity in the core accounting class d. What is the standard deviation of the number of students found to be in violation of academic integrity in the core accounting class?
| x | Prob(x) |
| 0 | 0.7 |
| 1 | 0.08 |
| 2 | 0.07 |
| 3 | 0.04 |
| 4 | 0.106 |
| 5 | 0.004 |
Based on historical data kept by a business school, the
a. Answer the questions below. Do your calculations in the columns to the right of Prob(x).
b. Is this a valid probability distribution? Justify briefly.
c. What is the
d. What is the standard deviation of the number of students found to be in violation of academic integrity in the core accounting class?
The two condition that need to be satisfied for any probability function is :
The probability against each value of x is greater than 0:
The sum of all the probabilities is 1 (0.7 + 0.08+0.07+0.04+0.106 +0.004)
Since, the two condition is satisfied it is a valid probability distribution
