To answer this question you will need to calculate the mean for each of the Shifts and then compare those means to the mean of all the data given. I have attached a picture of the means for each shift and the population mean (all the data).
Shift 1 is the closest to the population mean. It is 37.4, and the population mean is 35.9.

300 can be expected to prefer spaghetti over meatloaf.
Yes, it is kinda hard to explain so look this up--- linear equation calculator in equation form
Answer:
w = 37
Step-by-step explanation:
In order to solve for w you must add 14 to both sides which would be equivalent to w-14+14 = 23 + 14 which would be equal to w+0 = 37 or w = 37. This is allowed because of the addition property of equality which states that if the same number is added to both sides of an equation the equation will continue to be true.
Answer: 500 investigated @ 12%, 1,000 @ 13%, 1,500 @ 14%.
Process:
Suppose $x investigated at 12%, $y @ 13%, $(x+y) @ 14%.
According to the question we can set up the equations:
x+y+x+y=3000
0.12x+0.13y+0.14(x+y)=400
Solve it: x=500, y=1,000.
So x+y=1,500.
