What percent of the population values fall between 1 SD below and 1 SD above the mean? 2 SDs below and 2 SDs above? 3SDs below and 3 SDs above? Express your answers as a percentage with 2 decimal places. (Such as 25.36%) If we had a normally-distributed data set with the same mean and standard deviation, what should these percentages be? (Do not use the Empirical Rule...Actually calculate them with the normal distribution.) please give excel formula to calculate the following table.

What percent falls within ___ SDs of the mean?
