Answer:
a) 5.6 years
b) 0.4478
Step-by-step explanation:
We are given the following in the question:
Mean, μ = 5.6 years
Standard Deviation, σ = 1.9 years
Sample size, n = 18
We are given that the distribution of amounts of time is a bell shaped distribution that is a normal distribution.
a) Mean of each sample.
The best estimator of the sample mean is the population mean itself. Thus, we have:

Thus, the sample mean is 5.6 years.
b) Standard error
Formula:

Putting values, we have.

Thus, the standard error is 0.4478.
Answer: 
Step-by-step explanation:
To find the area of the shaded region, you must find the area of the larger rectangle [(x+10)×(2x+5)] and subtract the area of the smaller rectangle [(x+1)×(x+1)] from it.
First, you simplify the larger rectangle's area:
(x+10)×(2x+5) = 
Then, simplify the smaller rectangle's area:
(x+1)×(x+1) = 
Finally, subtract the smaller rectangle's area from the larger rectangle's area:

Therefore, the final answer is
.
