Use the range rule of thumb to identify a range of values containing the usual number of peas with green pods. Based on the result, is it unusual to get only one pea with a green pod? Explain.

Refer to the accompanying table, which describes results from eight offspring peas. The random variable x represents the number of offspring peas with green pods.
