Suppose a chi-square statistic testing for a relationship between two variables was found to be 1.746, with p-value 0.19 . What happens to the chi-square statistic and the resulting p-value if you triple the sample size?
a. The chi-square statistic triples and so does the p-value.
b. The chi-square statistic triples resulting in a smaller p-value.
c. The chi-square statistic goes up by a factor of 3 squared, and the p-value changes accordingly.
d. None of the above.

Question 2

Which of the following statements is false?
a. If the sample size is large enough, almost any null hypothesis can be rejected.
b. There is almost always a slight relationship between two variables, or a difference between two groups, and if you collect enough data, you will find it.
c. Larger samples sizes always produce more meaningful results than small sample sizes.
d. None of the above statements are false.
