You may need to use the appropriate appendix table to answer this question. Suppose that the mean daily viewing time of television is 8.35 hours. 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 3 and 10 hours a day? (Round your answer to four decimal places.) (b) How many hours of television viewing must a household have in order to be in the top 4% of all television viewing households? (Round your answer to two decimal places.) hrs (c) What is the probability that a household views television more than 5 hours a day? (Round your answer to four decimal places.) You may need to use the appropriate appendix table or technology to answer this question. A group conducted a survey of 13,000 brides and grooms married in the United States and found that the average cost of a wedding is $28,858. Assume that the cost of a wedding is normally distributed with a mean of $25,858 and a standard deviation of $5,200. (a) What is the probability that a wedding costs less than $20,000? (Round your answer to four decimal places.) (b) What is the probability that a wedding costs between $20,000 and $31,000? (Round your answer to four decimal places.) (c) What is the minimum cost (in dollars) for a wedding to be included among the most expensive 5% of weddings? (Round your answer to the nearest dollar.) $
