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
