Question

The time to fly between New York City and Chicago is uniformly distributed with a minimum of 120 minutes and a maximum of 150 minutes. What is the standard deviation?

Answer 1

8.66

Answer 2

Estimated SD = range/4

Answer 3

To find the standard deviation, we need to know the range (maximum - minimum) of the uniformly distributed data. In this case, the range is 150 - 120 = 30 minutes.

The formula to calculate the standard deviation for a uniform distribution is:

Standard Deviation = range / sqrt(12)

Plugging in the values, we get:

Standard Deviation = 30 / sqrt(12) ≈ 8.66 minutes

Therefore, the standard deviation for the flight time between New York City and Chicago is approximately 8.66 minutes.
