Of the 1023 adults surveyed, 536 indicated that televisions are a luxury they could do without. Complete parts (a) through (e) below. Click here to view the standard normal distribution table (page 1). Click here to view the standard normal distribution table (page 2). (a) Obtain a point estimate for the population proportion of adults in the country who believe that televisions are a luxury they could do without. p= 0.524 (Round to three decimal places as needed.) (b) Verify that the requirements for constructing a confidence interval about p are satisfied. sample size can be assumed to be less than or equal to The sample is stated to be a simple random sample, the value of np(1-P) is 261.593, which is greater than or equal to 10, and the 5% of the population size.
