Answer:
-0.91
Step-by-step explanation:
The z score formula is given as:
z = (x-μ)/σ, where
x is the raw score = 15 minutes
μ is the population mean = 17 minutes
σ is the population standard deviation = 2.2 minutes
z = 15 - 17/2.2
z = -2/2.2
z = -0.90909
Approximately = -0.91
The z-score for this amount of advertising time is -0.91
