Transcribed Image Text:### Understanding Television Viewing Probability
Suppose that the mean daily viewing time of television is 8.35 hours per household. Using a normal probability distribution with a standard deviation of 2.5 hours, answer the following questions about daily television viewing per household:
1. **What is the probability that a household views television between 6 and 9 hours a day?**
- Express your answer to 4 decimal places.
2. **How many hours of television viewing must a household have in order to be in the top 7% of all television viewing households?**
- Provide your answer to 2 decimal places.
3. **What is the probability that a household views television more than 4 hours a day?**
- Calculate the probability to 4 decimal places.
These questions explore the application of normal distribution in calculating probabilities and understanding viewing habits in households.
