a. The mean rate for satellite television for a sample of households was $70.00 per month, with a standard deviation of $14.50 per month. Between what two values do 99.7% of the data lie?

b. The mean rate for satellite television for a sample of households was $72.50 per month, with a standard deviation of $12.50 per month. Estimate the percent of satellite television rates between $60.00 and $85.00. (Assume the data set has a bell-shaped distribution.)
