Assuming that the population is normally distributed, construct a 90 % confidence interval for the population mean, based on the following sample size of n equals 6. 1, 2, 3, 4, 5, and 23 In the given data, replace the value 23 with 6 and recalculate the confidence interval. Using these results, describe the effect of an outlier (that is, an extreme value) on the confidence interval, in general. Find a 90 % confidence interval for the population mean, using...
