A study was conducted among 50 employees of a grocery
store looking at the probability of bladder cancer among those who
consume artificial sweeteners compared to those who do not. The
study found that the odds ratio was 5.9, and the p-value for
the chi-square test was 0.98. What would you conclude?
A. Those who drink artificial sweeteners have significantly higher
odds of getting bladder cancer compared to those who do
not.
B. Those who drink artificial sweeteners have significantly lower
odds of getting bladder cancer compared to those who do not.
C. Those who drink artificial sweeteners have higher odds of getting bladder cancer compared to those who do not, but the difference is not statistically significant.
D. Those who drink artificial sweeteners have lower odds of getting bladder cancer compared to those who do not, but the difference is not statistically significant.
Those who drink artificial sweeteners have higher odds of getting bladder cancer compared to those who do not, but the difference is not statistically significant.

Question 5 A recent case-control study compared the consumption of vitamins among those who infected with season influenza (cases) and those not affected by seasonal influenza (controls). The calculated odds ratios was. 0.61. The 95% confidence interval was 0.49-0.73. The most accurate interpretation of this result is: People who consume vitamins are 0.61 times more likely to contract seasonal influenza than those who do not consume vitamin. People who consume vitamins are 39% less likely to contract seasonal influenza than...
In the article "Coffee, Caffeine, and Risk of Depression Among Women" in the September 2011 edition of the Archives of Internal Medicine, researchers investigated the relationship between caffeine consumption and depression among women. The participants in this study were older, with substantially lower rates of depression when compared to female teens. Researchers compared two groups of women (among others) in this study: those who do not drink coffee and those who routinely drink 4 or more cups of coffee each...
CASE ONE The study is conducted to investigate the association between chewing tobacco and oral leukoplakia (a precancerous lesion) among currently active professional baseball players in the southeastern United States. A roster of all active players is obtained (n=500). All potential study subjects agree to participate. Each subject has an interview regarding current use of chewing tobacco and has his mouth examined by a dentist. Of the 500 subjects, 125 subjects chew tobacco and 375 do not chew tobacco. Of the...
A clinical trial is conducted to compare an experimental medication to placebo to reduce the symptoms of asthma. Two hundred participants are enrolled in the study and randomized to receive either the experimental medication or placebo. The primary outcome is self-reported reduction of symptoms. Among 100 participants who receive the experimental medication, 38 report a reduction of symptoms as compared to 21 participants of 100 assigned to placebo. When you test if there is a significant difference in the proportions...

People who eat lots of fruits and vegetables have lower rates of colon cancer than those who eat little of these foods. Fruits and vegetables are rich in "antioxidants" such as vitamins A, C, and E. will taking antioxidants help prevent colon cancer? A medical experiment studied this question with 864 people who were at risk of colon cancer. The subjects were divided into four groups: daily beta-carotene, daily vitamins C and E, all three vitamins every day,...

A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 318 people over the age of 55, 79 dream in black and white, and among 314 people under the age of 25, 13 dream in black and white. Use a 0.05 significance level to test the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25. Complete...
