Question

Suppose a population has a mean of 7 for some characteristic of interest and a standard deviation of 9.6. A sample is drawn from this population of size 64. What is the standard error of the mean?

Answer 1

1.2

Step-by-step explanation:

The formula to compute the standard error of the mean is shown below:

Standard error formula equals to

`=(standard\ deviation)/(√(Population\ size))`

`=(9.6)/(√(64))`

`=(9.6)/(8)`

= 1.2

It shows the relationship between the standard deviation and the population size. The population mean is ignored while computing the standard error
