Answer:0.25
Step-by-step explanation:
Just type it in a calculator
4116 first answer 7 times 8 subtract 35.Second multiply by 14.Lastly solve 7 times 2 and multiply it by what you got multiplying 14.
Part A - 226.865 or 226.87
Part B - 120
Part C - 106.865
If you would like to know the average earning per week, you can calculate this using the following steps:
525 + 575 + 475 = 1575
1575 / 3 = 525
The correct result would be $525.
It can't be A. since if you only look at managers, you are missing all the sales executives.
It may be C. this option is more random but doesn't guarantee that you will represent both groups of employee's. Also, each time you would conduct the survey, you will receive the exact same results since it is the same people.
It isn't D. for the exact same reason as A. but you're missing managers now.
Therefore the answer is B. Some managers and some sales executives selected at random. This way you get a sample from both categories, and within those groups, it is randomly selected.
I hope this helps!
