Further, twenty pecple ate the three- bean salad (5 did not), and 7 of thern are complaining of diarrhea. Of those that did not eat the three-bean salad, 5 report diarrhea. 43. (2 points) Construct a 2 x 2 table for the exposure of venison and the outcome of diarrhea. Diarrhea No Diarrhea Total Venison No Venison 44. (2 points) Calculate and interpret the relative risk for assessing the relationship between eating venison and getting diarrhea. 45. (2 points) Construct a 2 x 2 table for the exposure of three-bean salad and the outcome of diarrhea No Diarrhea Total Three-bean salad No three-bean salad Total 46. (2 points) Calculate and interpret the relative risk for assessing the relationship between eating three bean salad and getting diarrhea.

Answer 1

43) From the above information the otcome of diarrhea due to venison is calulated below :

43. (2 points) Construct a 2 x 2table for the exposure of venison and the outcome of diarrhea Total 13 12 25 Diarrhea 10 No Diarrhea Venison No Venison Total 10 13 12

Here the people suffered with diarrhea is 12 and with no diarrhea is 13.

44) The 12 people out of 25 suffered with diarrhea due to exposure to venison .

The risk of getting diarrhea due to venison is more because 10 people among 12 is suffered with diarrhea.

45) The outcome of diarrhea due to three bean salad is calculated below :

45. (2 points) Construct a 2 x 2 table for the exposure of three-bean salad and the outcome of diarrhea Diarrhea No Diarrhea 13 0 13 Total 20 Three-bean salad No three-bean salad Total 12 25

Here the people with diarrhea due to three bean salad is 12 and no diarrhea is 13.

46) Here the 12 people out of 25 suffered with diarrhea among them 7 out of 12 due to three bean salad .

Where remaining 5 are not due to three bean salad .

So the risk of getting diarrhea due to three bean salad is less when compared to venison.
