## How do you find the point estimate of the population mean?

Suppose that you want to find out the average weight of all players on the football team at Landers College.

You are able to select ten players at random and weigh them.

The mean weight of the sample of players is 198, so that number is your point estimate.

Assume that the population standard deviation is σ = 11.50.

## What is the function of a point estimate?

In statistics, point estimation involves the use of sample data to calculate a single value (known as a point estimate since it identifies a point in some parameter space) which is to serve as a “best guess” or “best estimate” of an unknown population parameter (for example, the population mean).

## What is the point estimate for this 95 confidence interval?

The point estimate for the population proportion is the sample proportion, and the margin of error is the product of the Z value for the desired confidence level (e.g., Z=1.96 for 95% confidence) and the standard error of the point estimate.
