Answer:
75% of college students exceed 6.63 minutes when trying to find a parking spot.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 10 minutes
Standard Deviation, σ = 5 minutes
We are given that the distribution of time for parking is a bell shaped distribution that is a normal distribution.
Formula:

P(X < x) = 0.25
We have to find the value of x such that the probability is 0.25.
P(X < x)
Calculation the value from standard normal z table, we have,

Hence, 75% of college students exceed 6.63 minutes when trying to find a parking spot.
The answer would be positive 5
The product of this is 81
