Public relation companies conducted two surveys about deodorants. The first survey asked a random sample of 500 men about their use of a natural deodorant. A second survey asked the same questions to a random sample of 550 women. In these two studies, 68% of men and 44% of women stated they were dissatisfied with the effectiveness of natural deodorants. Use these results to answer the following questions about the proportion of men and women's satisfaction with natural deodorants. (Round to the nearest whole person as needed). Is there a statistically significant difference between men and women's satisfaction with natural deodorants? Yes, the proportion of men that are satisfied with natural deodorants is significantly less than the proportion of women that are satisfied with natural deodorants because both the lower limit and the upper limit of the confidence interval are positive values. Yes, the proportion of men that are satisfied with natural deodorants is significantly more than the proportion of women that are satisfied with natural deodorants because both the lower limit and the upper limit of the confidence interval are negative values. Yes, the proportion of men that are satisfied with natural deodorants is significantly more than the proportion of women that are satisfied with natural deodorants because both the lower limit and the upper limit of the confidence interval are positive values. Yes, the proportion of men that are satisfied with natural deodorants is significantly more than the proportion of women that are satisfied with natural deodorants because both the lower limit and the upper limit of the confidence interval are negative values.

Question
### QUESTION 6 **Context:** Public relation companies conducted two surveys about deodorants. The first survey asked a random sample of 500 men about their use of a natural deodorant. A second survey asked the same questions to a random sample of 550 women. In these two studies, 68% of men and 44% of women stated they were dissatisfied with the effectiveness of natural deodorants. Use these results to answer the following questions about the proportion of men and women's satisfaction with natural deodorants. *(Round to the nearest whole person as needed).* **Question:** Is there a statistically significant difference between men and women's satisfaction with natural deodorants? **Options:** - ○ Yes, the proportion of men that are satisfied with natural deodorants is significantly less than the proportion of women that are satisfied with natural deodorants because both the lower limit and the upper limit of the confidence interval are positive values. - ○ Yes, the proportion of men that are satisfied with natural deodorants is significantly more than the proportion of women that are satisfied with natural deodorants because both the lower limit and the upper limit of the confidence interval are negative values. - ○ Yes, the proportion of men that are satisfied with natural deodorants is significantly more than the proportion of women that are satisfied with natural deodorants because both the lower limit and the upper limit of the confidence interval are positive values. - ○ Yes, the proportion of men that are satisfied with natural deodorants is significantly more than the proportion of women that are satisfied with natural deodorants because both the lower limit and the upper limit of the confidence interval are negative values. - ○ No, there is no difference between the proportion of men that are satisfied with natural deodorants and the proportion of women that are satisfied with natural deodorants because both the lower limit and the upper limit of the confidence interval are positive values. *(Note: The correct choice will depend on statistical analysis which includes calculating the confidence intervals for the satisfaction proportions for both men and women.)*
