A study, which randomly surveyed

3,500

households and drew on this information from the CRA (Canada Revenue Agency), found that

73%

of households have conducted at least one pension rollover from an employer-sponsored retirement plan. Suppose a recent random sample of

110

households in a certain county was taken and respondents were asked whether they had ever funded a RRSP account with a rollover from an employer-sponsored retirement plan. Based on the sample data below, can you conclude at the

0.05

level of significance that the proportion of households in the county that have funded an RRSP with a rollover is different from the proportion for all households reported in the study?

89

respondents said they had funded an account;

21

respondents said they had not
