Question
The time it takes a person to recover from a cold is normally distributed with a mean of 8.9 days and
a standard deviation of 0.7 days.
1. Suppose an individual with a cold is randomly selected. What is the probability that they
recover within 8.8 days?
o What distribution will you use to calculate this probability?
N( 8.9
07
o List the z-scores needed to calculate the result. If there is more than one z-score,
separate the values with a comma.
-0.143
o There is a 4443
x chance that the individual recovers within 8.8 days.
2. Suppose 97 individuals with colds are randomly selected. What is the probability that, on
average, they recover within 8.8 days?
o What distribution will you use to calculate this probability?
N 8.9
.071
o List the z-scores needed to calculate the result. If there is more than one z-score,
separate the values with a comma.
-1.40845
o There is a .071
x chance that the 97 individuals with recover within an
average of 8.8 days.
