Ответ:
(a)
(b) The best point estimate of is the sample mean
The margin of error = 4.552
Step-by-step explanation:
Given : The confidence interval for the population mean = (13.046 , 22.15)
Sample mean :
Standard deviation :
Sample size :
a. Let represents the population mean.
Then we can write the confidence interval for the population mean as :-
b. The best point estimate of is the sample mean
Also, the lower limit of confidence interval can be written as
i.e.
Hence, the margin of error = 4.552
