Liposuction Statistics
Tuesday, March 15th, 2011Primary statistics short exercise?
Hi, I understand that this is the very basis of mathematics but still, I am not able to understand this problem out. Statistics started my first night of classes, which have a poor knowledge of mathematics, but really I have to understand everything from the beginning. The problem is as follows: USA Today-type chart shows the most common cosmetic surgeries for women in 2003. – Liposuction 21% – 18% increase Breast – eyelid surgery 14% – Breast Reduction 9% (a) If women had 1,548,000 cosmetic surgeries in 2003, how many of them were for liposuction? (B) How many were for eyelid surgery? (C) What percentage of surgeries are not taken into account in the chart? If possible, I would like an explanation of how. I'm not interested in the results themselves, but in the process. The professor was lecturing on last night frequency and relative frequency. Thank you very much.
We're assuming it's a woman, otherwise surgery gets tough! To calculate the percentage to multiply by the number and divide by 100. Thus, on one hand the number of women who have had liposuction is 1,548,000 x 21/100 = 325 080 the same process to the b, eyelid surgery. You can work one! In total there are 100% to account for so for part c you just add the other numbers and take that number out 100. ie 100-62 = 38%
