The cash operating expenses of the regional phone companies during the first half of 1994 were distributed about a mean of $29.92 per access line per month, with a standard deviation of $2.15. Company A's operating expenses were $28.00 per access line per month. Assuming a normal distribution of operating expenses, estimate the percentage of regional phone companies whose operating expenses were closer to the mean than the operating expenses of Company A were to the mean.
