Answer:
D) 56 inches to 74 inches
Step-by-step explanation:
By the Empirical Rule, 99.7% of data in a normal distribution spread across ±3σ standard deviations from the mean μ.
Hence, the range maximum is μ+3σ = 65+3(3) = 65+9 = 74 inches, and the range minimum is μ-3σ = 65-3(3) = 65-9 = 56 inches
Thus, 99.7% of the population will have a height within the range of 56 inches to 74 inches
