A study that randomly surveyed 3.500 households found that 37% of households have funded at least one IRA rollover from an employer-sponsored retirement plan. Suppose a recent random sample of 50 households in a metropolitan area was taken and respondents were asked whether they had ever funded an IRA account with a rollover from an employer-sponsored retirement plan. The results are available in the accompanying table Complete parts a through c below. Click the icon to view the survey results. Click the icon to view a table of critical values for commonly used confidence levels a. Based on the random sample, what is the best point estimate for the proportion of all households in the metropolitan area that have ever funded an IRA account with a rollover from an employer-sponsored retirement plan? The best point estimate for the proportion is (Type an integer or a decimal) b. Construct a 99% confidence interval estimate for the true population proportion of households in the metropolitan area that had ever funded an IRA account with a rollover from an employer-sponsored retirement plan ♫ (Round to three decimal places as needed. Use ascending order)
