These exercises use the normal probability density function and requires the use of either technology or a table of values of the standard normal distribution. a. The cash operating expenses of the regional phone companies during the first half of 1994 were distributed about a mean of $29.78 per access line per month, with a standard deviation of $2.15. Company A's operating expenses were $29.00 per access line per month. Assuming a normal distribution of operating expenses, estimate the percentage...
