The distribution of marks scored by a large class in an exam can be represented as a normal distribution with mean μ and standard deviation σ. In a follow-up exam in the same class, everyone scored 5 marks more than their respective score in the earlier exam. For this follow-up exam, the distribution of marks can be represented as a normal distribution with mean μ2 and standard deviation σ2. Which one of the following is correct?
| X | 1 | 2 | 3 | 4 |
|---|---|---|---|---|
| P(X) | 0.3 | 0.4 | 0.2 | 0.1 |
| X (in Rs.) | -100 | 0 | 100 | 500 |
|---|---|---|---|---|
| P (X) | 0.25 | 0.5 | 0.2 | 0.05 |
