Question

You may need to use the appropriate appendix table or technology to answer this question. The following sample data are from a normal population: 8, 6, 10, 13, 11, 9, 4, 3. (a) What is the point estimate of the population mean?

Answer 1

The point estimate of the population mean based on the provided sample data is 8.25.

Step-by-step explanation:

The student is asking about the point estimate of the population mean based on a given sample. The calculation involves averaging the sample data. In the provided sample data (8, 6, 10, 13, 11, 9, 4, 3), the point estimate of the population mean (μ) is the sample mean.

To find it, you sum up all the sample values and divide by the number of observations. Thus, the point estimate of the population mean is (8 + 6 + 10 + 13 + 11 + 9 + 4 + 3) ÷ 8 = 8.25.
