Suppose 40% of investors have funded a Roth IRA rollover from an employer-sponsored retirement account.

The HR manager for a Florida company selected a random sample of 90 households in the greater Miami area, and respondents were asked whether they had ever funded a Roth 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 a Roth IRA with a rollover is different from the proportion for all households reported in the study?
