A study by the Investment Company Institute (ICI) in 2004, which randomly surveyed 3,500 households and drew on information from the IRS, found that 72% of households have conducted at least one IRA rollover from an employer-sponsored retirement plan (www.

Suppose a recent random sample of 90 households in the greater Miami 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 in the file Miami Rollover. Based on the sample data, can you conclude at the 0.10 level of significance that the proportion of households in the greater Miami area that have funded an IRA with a rollover is different from the proportion for all households reported in the ICI study?
