Final answer:
The point estimate of the population mean can be calculated by taking the average of the sample data, in this case, the sample data are 6, 8, 10, 8, 11, 5. The point estimate is 8.
Step-by-step explanation:
The point estimate of the population mean can be calculated by taking the average of the sample data. In this case, the sample data are 6, 8, 10, 8, 11, 5. Adding these values together gives a sum of 48. Dividing this sum by the sample size, which is 6, gives a point estimate of the population mean of 8.
