Question

In a normal distribution with a mean of 30 and a standard deviation of 5, you'd find the largest distribution of cases between: a) 25 and 35 b) 20 and 40 c) 15 and 45 d) 10 and 50

Answer 1

Explanation:

a) 25 and 35

This range covers one standard deviation below the mean (30 - 5 = 25) to one standard deviation above the mean (30 + 5 = 35) and typically includes approximately 68% of the cases in a normal distribution.
