The diagram below shows a graph of a normal curve. The mean and the number of standard deviations from the mean are labeled below the graph. The red dashed lines correspond to the different values. Given that the mean is 61 and the standard deviation is 6, fill in the answerboxes below the labels with their corresponding values. Then answer the questions below the graph about the Empirical Rule. -3 sd -2 sd -1 sd According to the Empirical Rule, Approximately 68% of the data values fall between Approximately 95% of the data values fall between Approximately 99.7% of the data values fall between mean +1 sd and and and +2 sd +3 sd
