Answer to Question #293823 in Statistics and Probability for Angel

Question

A sample of 60 Grade 11 students' ages was obtained to estimate the mean of all Grade 11 students. The sample mean is 16.4 years and the population standard deviation is 4. What is the point estimate for µ?

Answer 1

Given : Sample mean= 16.4

Sample size= 60

population mean = 11

population sd=4

The sample mean $\overline{x}$ is a point estimate of the population mean, μ.

Hence the point estimate for µ=16.4
