Answer:
Odds of being a case = 1.90
Step-by-step explanation:
Relationship between artificial sweeteners and bladder cancer.
Amongst the cases, 1,293 had used artificial sweeteners in the past, while 1,707 had never used artificial sweeteners.
used AS = 1,293
Not used AS = 1,707
Among the controls, 855 had used sweeteners and 2,145 had not.
We can prepare a table from the above information,
Cases Controls
used AS a = 1,293 b = 855
Not used AS c = 1,707 d = 2,145
The odds of being a case may be calculated as
[tex]$ odds = \frac{a \times d}{b \times c} $[/tex]
[tex]$ odds = \frac{1,293 \times 2,145}{855 \times 1,707} $[/tex]
[tex]odds = 1.90[/tex]
Therefore, we can conclude that a person having bladder cancer used artificial sweeteners was 1.90 times the odds that a person without bladder cancer used artificial sweeteners .
