Correct answer is: P(x<6) is 0.123 and it is usual.
Solution:-
Given that the time a person takes to decide which shoes to purchase follows normal distribution. Which has mean = 8.21 minutes and standard deviation 1.90
Then probability of individual takes less than 6 minutes is
P(X<6) = 
= 
= 0.1230
Typically we say an event with a probability less than 5% is unusual.
But here P(X<6) = 0.123 is greater than 5% hence this is usual.

Answer:
C
Step-by-step explanation:
A, B are wrong since 8,795 is a constant, it doesn’t change;
D is wrong since it is the starting cost, not total cost
Answer:
5/42 is your answer take robot to complete
7 tasks = 5/6
1 task = 5/42 hour.
1 hour / (5/42 hour/task) = 15/2 tasks = 8.2 tasks.
half a task isn’t a complete task, so the answer is 8 tasks.
