A sample of 200 individuals are tested for their blood type is given in the first table, and the results are used to test the hypothesized distribution of blood types. The observed results are given in the second table. At the .05 level of significance, is there sufficient evidence to show that the stated distribution is incorrect?
| Blood Type | Â Â A Â Â | Â Â B Â Â | Â Â O Â Â | Â Â AB Â Â |
| Percent | 0.39 | 0.06 | 0.38 | 0.17 |
| Blood Type | Â Â A Â Â | Â Â B Â Â | Â Â O Â Â | Â Â AB Â Â |
| Number | 69 | 15 | 82 | 34 |
