Question

Suppose that a study of elementary school students reports that the mean age At which children begin reading is 5.6 years with the standard deviation of 1.1 years. If a sampling distribution is created using samples of ages at which 53 children begin reading what will be the meanof the sampling distribution of sample means? Round to two decimal places of necessary

Answer 1

The population mean age is given: 5.6 years.

When we sample this population with any number n of people and calculate the mean, we will have a sample mean, and this mean has the same value as the population mean.

Therefore the sample mean is equal to 5.6 years.
