determine the point estimate of the population mean and the margin of error for the given confidence interval. lower bound: 12 upper bound: 20

Respuesta :

The required point estimate of the population mean and the margin of error are 16 and 4.

How to solve the point estimate of the population mean and the margin of error?

The point estimate is the value of a statistic that estimate the value of the parameter.

According to given data in the question:

Given, lower point =12, upper point = 20

we know that

Population mean(x) = 12+20/2 = 16

And formula for margin o error,

x + E = upper point  , x - E = lower point

Then, 16 + E = 20

E = 4

Similarly, 16 - E = 12

E = 4

Hence, population mean and margin of error are 16 and 4 respectively.
