Question

A scientist is studying a gene implicated in cancer in mice. She samples 14,000 mice and her p-value is 5%. What should her conclusion be?

Answer 1

Answer:

In conclusion the scientist should state that the data suggests that the gene causes cancer in mice.

Explanation:

A p-value is a measure of significance, it is the probability of the findings giving a false-positive of the hypothesis. A p-value less than or equal to 0.005 (5%) is considered significant. In conclusion the scientist should state that the data suggests that the gene causes cancer in mice.

Answer 2

The given values are 14,000 sample size and 5% p-value. Statistical significant results are achieved when p-value is less than the significance level. This shows a 95% confidence of results in the samples. The rejection region is composed of 5% of the sample distribution.
