Use a normal probability distribution with a standard deviation of 2.5 hours to answer the following questions about daily television viewing per household. a. What is the probability that a household views television between 4 and 10 hours a day (to 4 decimals)? b. How many hours of television viewing must a household have in order to be in the top 7% of all television viewing households (to 2 decimals)? hours c. What is the probability that a household views television more than 2 hours a day (to 4 decimals)?
