Given the parameters of the population proportion distribution andsample standard deviation, generate the bootstrapconfidence interval. In this situation, we’re basically using r like an error interval calcula
to find the lower and upper limit of the confidence interval. For example, you would subtract 3.344 from the mean of 91.5 to find the lower limit to be 88.2, and add it to find the upper limit to be 94.8. This range, 88.2 to 94.8, is your confidence interval for the mean...
enter "=D1+(1.96D4)" into a blank cell to get the result. To find the lower bound, choose another empty cell and enter "=D1-(1.96D4)." Note that this returns the 95 percent confidence interval. If you want the
