Find the interval W +-/- 2SW where W stands for the WEIGHT variable, Sw stands for the standard deviation of W. What fraction of the sample (as a decimal) lies within the interval? Give your answer to 4 decimal places (note -- I do not want a percentage) Hint: Notice that this is not asking a theoretical question concerning the empirical rule but rather what is the case for this sample. You will need to use the square brackets "" well. Make a boolean expression that returns TRUE for each datum in the interval.
