An airline has two flights each day from City A to City B. A random sample of 10 morning flights left the gate an average of 15 minutes late with a standard deviation of 5 minutes. A random sample of 10 evening flights left the gate an average of 20 minutes late with a standard deviation of 3 minutes. Suppose both the morning and evening flights are 30 minutes late. To determine which flight is more late than usual, first find the z-scores. Round to one decimal place if necessary.

Step-by-step explanation:

Let X denote the random variable that obeys the normal distribution.

Given that:

For morning flights

Mean = 15

standard deviation = 5

Sample size = 10

The Z - score is calculated as:

Z = 3

For evening flights

Mean = 20

standard deviation = 3

Sample size = 10

Z = 3.33

Hence, from the above z-scores, we will realize that the evening flight is more late than usual.
