------------------------------------------------ A population has a mean of 37 with a standard deviation of 9. A sample of 50 items from that population has a mean of 35.5 with a standard deviation of 11.

Which equation describes the point estimate?

A. μ = 37
B. = 37
C. = 35.5
D. = 35.5

Answer :

The equation that describes the point estimate of the population mean is x = 35.5

Which equation describes the point estimate?

From the question, we have the following parameters that can be used in our computation:

  • A population has a mean of 37 with a standard deviation of 9.
  • A sample of 50 items has a mean of 35.5 with a standard deviation of 11.

As a general rule

The point estimate of the mean equals the sample mean

This means that

Point estimate = 35.5


Hence, the equation is x = 35.5
