Question

A study conducted on a college campus tested to see whether students with colds who are given large doses of vitamin C recover faster than students who are not given the vitamin C. The p value for the test is 0.003.

A. Given the p value, what is the conclusion of the test? Reject H0 or do not reject H0?

B. Results of statistical inference are only as good as the data used to obtain the results. No matter how low a p value is, it has no relevance (and we can't trust conclusions from it) if the data were collected in a way that biases the results. Describe an inappropriate method of collecting the data for this study that would bias the results so much that a conclusion based on the p value is very unreliable.

C. Describe a method of collecting the data that would allow us to interpret the p value appropriately and to extend the results to the broader student population.

D. Assuming the data were collected as you describe in c, use the p value to make a conclusion about vitamin C as a treatment for students with a common cold.

Answer 1

From the given information above ,

The P value is 0.003.

The P value is less than 0.05. We reject the null hypothesis .

We can use a primary method to collect the data points to taking surveys or interviewed students.

Sample size should be large enough to analyze the test.
