Which of the Statistical Principles Stated Below Is False

Which of the statistical principles stated below is false?

A) A statistically significant finding does not necessarily have practical significance or importance. When a study reports a statistically significant finding, we also need to find out the magnitude of the result.
B) A change in the rate or risk of occurrence of something is only useful when the base rate or baseline risk is reported as well.
C) When you read about a reported relationship or difference, you also need to find out how many different things were tested. The more tests that are done, the more likely it is that a statistically significant difference is a false positive that can be explained by chance.
D) Sample sizes are dependent on population sizes. So, in order to give reasonably accurate information about a population of many millions, we have to take a sample of many thousands.
