Answer:
The scores are equal
Explanation:
The z-score for any normal distribution is:

(i) Score (X) = 40
Mean (μ)= 50
Standard deviation (σ) = 10

(ii) Score (X) = 45
Mean (μ)= 50
Standard deviation (σ) = 5

Both scores have the same z-score, which means that, relative to their respective distributions, the scores are equal.
