Question

A screenting study is performed to determine the prevalence of colon cancer in 10000 subjects in a rural community. Researchers are examining the efficacy between a fecal occult blood stool sampling and a colonoscopy. The two tailed test with a p value of 0.025 and a 95% confidence interval indicates that the colonoscopy screening provides a higher rate of early detection. Researchers have found that allowing the participant to select the screening test did not affect the findings compared to previous results. How does sample size affect the report? (Please explain the answer in detail) Choose 2 answers. 1) The sample size is adequate for generalizability to the population. 2) The sample size is to large to handle the population effectively. 3) The sample size is too small for the population in this study. 4) The sample size is large emough to show statistical significance. Please explain the answer in detail.

Explanation / Answer

1. The sample size is adequate for generalisability to the population

And 4. The sample size is large enough to show statistical significance

The sample size is 10000 , which is very large so we can say that it is nearly the size of the population .

Though we got the result to be significant, and the test claimed colonoscopy helps in early detection but the sample size is too large to come to a conclusion.
