Step-by-Step Solution:
Step 1 of 3

Solution 8E

Step1 of 3:

We have company in that every worker recieved a $50 per week raise. We need to check How does this affect the mean salary? and The standard deviation of the salaries? Step2 of 3: Let be the old salary of workers. 1).Mean of the X is given by: Where, = Mean x = random variable N = sample size = 3. Now, = = = Hence, = . Therefore, the mean salary is raised by$50.

Step3 of 3:

2). Standard deviation of X is given by:

=

=

Hence, =

Therefore, standard deviation will be same.
