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 deoderants.  (Round to the nearest whole person as needed).
