Answer:
0.7745
Step-by-step explanation:
Given that the length of time it takes college students to find a parking spot in the library parking lot follows a normal distribution with a mean of 3.5 minutes and a standard deviation of 1 minute.
X, the length of time is N(3.5, 1)
The probability that a randomly selected college student will take between 2 and 4.5 minutes to find a parking spot in the library lot.
= [tex]P(2<x<4.5)\\=F(4.5)-F(2)[/tex] where F represents the cumulative probability upto that value
=
[tex]0.8413-0.0668\\=0.7745[/tex]
Answer is 0.7745
