Determine the point estimate of the population mean and margin of error for the confidence interval. Lower bound is 17 , upper bound is 25. The point estimate of the population mean is: The margin of error for the confidence interval is:

Population mean = 21

Margin of error = 4

Step-by-step explanation:

Given that

Lower bound of the population is 17

Upper bound of the same population is 25

The population mean, x-bar is calculated by saying

x-bar = (lower bound + upper bound)/2

x-bar = (17 + 25)/2

x-bar = 42/2

x-bar = 21

Margin of error for the confidence interval is gotten by

E = (upper bound - lower bound)/2

E = (25 - 17)/2

E = 8/2

E = 4

Thus, the mean is 21, while the error is 4
