TRUE OR FALSE
1.The x^2 is a good test to use when we have this kind of hypothesis: H0: s2 = 34.6 in2
2.We also use the x^2 as a goodness of fit test, as for distribution shapes.
3.If two variables represent a cause-&-effect relationship, then they will have a significant correlation.
4.A significant r = -0.473 is as valuable to us as a significant r = +0.473.
5.We use the F-Test: Two Samples for Variances to help us which of two subsequent t-tests to use.
Solution
False. Chi square test is used to test population standard deviation or variances. True False. Correlation does not imply causation. True True
