The best estimate of the population means is always the sample mean. We have the sample values, using them we can find the sample mean.
The sum of the sampled rates = 248
Sample Size = 10
Mean value of the sample = Sum of Sample Rate/Sample Size
So,
Mean of the sample = 248/10 = 24.8
Therefore, we can say that the best estimate for the population mean is 24.8
a)
because it is equal to the area of the shaded region between X=4 and X=6, and the probability that X falls within some interval is given by the area under the PDF.
b)
because the shaded region is a rectangle of height 1/5 (by virtue of X following a uniform distribution over the interval [2, 7], which has length 5).
we know that
To find the company with the greatest total employee compensation package, adds each company's gross pay, paid insurance, and paid time off, then subtract the job expenses on the sum
So
Find the total employee compensation package for each company
Step 
Find the total employee compensation package for company A


Step 
Find the total employee compensation package for company B


Step 
Find the total employee compensation package for company C


Step 
Find the total employee compensation package for company D


therefore
the answer is
the company with the greatest total employee compensation package is the company C
It depends on what way the figure is translated, but it's possible it could be a dilations, reflection, rotation, etc.
Answer:
