Tim Worker is doing his budget. He discovers that the average electric bill for the year was $206 with a standard deviation of $10.00. What percent of his expenses in this category would he expect to fall between $184.00 and $200.00? The z for $184.00 = - .62.22 . The percent of area associated with $184.00 = 62.2 %. The z for $200 = - .622.22 . The percent of area associated with $200 = 48.6 %. Subtracting the two percentages, the percent of expenses between $184.00 and $200.00 is 622.22
