The data to the right represent the weights (in grams) of a random sample of 50 candies. Complete parts (a) through (f).
(a) Determine the sample standard deviation weight.
b) On the basis of the histogram to the right, comment on the appropriateness of using the Empirical Rule to make any general statements about the weights of the candies.
- The histogram is approximately bell-shaped so the Empirical Rule cannot be used.
- The histogram is not approximately bell-shaped so the Empirical Rule cannot be used.
- The histogram is not approximately bell-shaped so the Empirical Rule can be used.
- The histogram is approximately bell-shaped so the Empirical Rule can be used.
