The following data are from a simple random sample: 5, 8, 10, 7, 10, 14. What is the point estimate of the population mean? |
8.5 9 9.5 10 |
9 |
The correct answer is Option (2) → 9 Given sample data is 5, 8, 10, 7, 10, 14 and n = 6. The point estimate of population mean is sample mean. $∴\bar x=\frac{Σx_i}{n}=\frac{5+8 +10 + 7 + 10 + 14}{6}$ $=\frac{54}{6} = 9$ |
