Stats 10 Homework #2 2.20 Acura has higher mpg, BMW has more variation because the data is more spread out 2.22 1. A 2. C 3. B 2.38 1. 7.5 million 2. 5.2 million 3. No it suggest high blood pressure 4. Parmuda chart? 2.42 1. 27% 4+21+2 2. 8% 36-28 pie chart was better because it involved less estimation and had more specific percentages 2.50 1. Bar graph because it is not touching 2.

3.16 New York has more variation while LA has a higher typical temperature. We know this because LA has more data within the meanwhile New york is more spread out. 3.24 a. Florida is typically more expensive with the average cost for housing being 244.3 and GA being 206.4 b. Florida has more variation. c. I predict without the high price house in Florida, the standard deviation would show a smaller amount of variation. My prediction was correct, with all the data standard deviation for FL is 86.43132 and without the 432.4 house, the standard deviation is 68.32127
