mean is called the 9. Suppose a population consisted of 20 items. How many different sample of n = 3 are possible? 10. A point estimate is 11. We wish to develop a confidence interval for the population mean. The population follows the normal distribution‚ the standard deviation of the population is 3‚ and we have a sample of 10 observations. We decide to use the 90 percent level of confidence. The appropriate value of to represent the level of confidence is 12. A confidence interval
