Answer:
The z score for the airplane arriving 13 minutes after arrival time is 0.33
Step-by-step explanation:
Using normal distribution,
The average lateness for one of the top airline companies is 10 minutes. So our mean, u = 10
The variance, s of the lateness measure is calculated as 9.
x =13 which stands for arrival time.
Using normal distribution,
z = (x - u)/s
z = (13 - 10)/9 = 3/9 = 0.33
The z score for the airplane arriving 13 minutes after arrival time is 0.33. The probability value of the z score can be found by looking at the Normal distribution table
