Answer:
$29765.50
Step-by-step explanation:
Median is the middlemost value (or the average of the 2 middlemost value if there are even number of values) in an ascending order.
First, arrange the salary list in an ascending order.
$21,971 , $25,997 , $27,512 , $32,019 , $38,860 , $43,702
As we can see here, there are even number of values (6), so the median will be the average of the 2 middlemost value, which will be:
Median = 
= 
= $29765.50

Answer:
The mean of the total repair time is 150 minutes.
The variance of the total repair time is 725 minutes^2.
Step-by-step explanation:
To solve this problem, we have to use the properties of the mean and the variance. Our random variable is the sum of 3 normal variables.
In the case, for the mean, we have that the mean of the sum of 3 normal variables is equal to the sum of the mean of the 3 variables:

For the variance, we apply the property for the sum of independent variables (the correlation between the variables is 0):

Composite, it can be divided
