Question 5 10 pts The length of time it takes to find a parking space at 10 A.M. follows a normal distribution with a mean of five minutes and a standard deviation of two minutes. Find the probability that it takes at least eight minutes to find a parking space. 0.0668 0.9270 0.5001 0.0001 10 pt= Question 6

Answer 1

$P[X\geq 8]$

$=P[Z\geq \frac{8-5}{2}]$

$=P[Z\geq 1.5]$

$=1-P[Z<1.5]$

=1-0.9332......................by using Z table.

=0.0668

0.0668
