A random sample of 1026 adults in a certain large country was asked "Do you pretty much think televisions are a necessity or a luxury you could do without?" Of the 1026 adults surveyed, 533 indicated that televisions are a luxury they could do without. Complete parts (a) through (e) below. A. There is a % probability the proportion of adults in the country who believe that televisions are a luxury they could do without is between and B. We are 95% confident the proportion of adults in the country who believe that televisions are a luxury they could do without is between 0.488 and 0.550 (d) Is it possible that a supermajority (more than 60%) of adults in the country believe that television is a luxury they could do without? Is it likely? It is possible, but not likely that a supermajority of adults in the country believe that television is a luxury they could do without because the 95% confidence interval does not contain 0.6. (Type an integer or a decimal. Do not round.) (e) Use the results of part (c) to construct a 95% confidence interval for the population proportion of adults in the country who believe that televisions are a necessity. Lower bound:, Upper bound: (Round to three decimal places as needed.)
