Question

What is the standard deviation (σ) of the ages of airline passengers if the mean (μ) is 41 and x = 95?

A) 13
B) 54
C) 95
D) 41

Answer 1

The standard deviation of the ages of airline passengers is 54. Option B is the correct answer.

Step-by-step explanation:

To find the standard deviation of the ages of airline passengers, we need to use the formula:

σ = √[∑(x-μ)²/N]

Where σ is the standard deviation, x is each age, μ is the mean age, and N is the number of passengers. From the given information, we have μ = 41 and x = 95. Plugging these values into the formula, we get:

σ = √[(95-41)²/1] = √[2916] = 54

Therefore, the standard deviation of the ages of airline passengers is 54 (option B).
