Answer: 0.0918, it is not unusual.
Step-by-step explanation:
Given : The length of time a person takes to decide which shoes to purchase is normally distributed with a mean of 8.54 minutes and a standard deviation of 1.91.
i.e. minutes and
minutes
Let x denotes the length of time a person takes to decide which shoes to purchase.
Formula :
Then, the probability that a randomly selected individual will take less than 6 minutes to select a shoe purchase will be :-
Thus , the required probability = 0.0918
Since, P-value (0.0918) >0.05 , it means this outcome is not unusual.
[Note : When a outcome is unusual then the probability of its happening is less than or equal to 0.05. ]
