In the histоgrаm belоw the meаn is 55, the stаndard deviatiоn is 20, and 21% of the Cost of Living scores are between 45 and 65. The Normal curve having a mean of 55 and a standard deviation of 20, N(55,20) is also shown. Fill in the blank in the following statement: Using this Normal curve N(55,20) as a model for the histogram, the percentage of the Cost of Living scores between 45 and 65, is 21%.
