Answer to Question 1

D

Answer to Question 2

The validity of any statistical result or conclusion depends on the validity of the sampling procedure, and the data collection process.
Example: A researcher wants to determine which candidate is being favored in the next presidential election, so she goes to the mall on Saturday and asks the first 100 people she sees. Her results are not credible because she used a biased sample.
