TRUE OR FALSE??

48-The power curve plots ? on the Y axis and the test statistic on the X axisx

2-When ? is unknown, it is more conservative to use z instead of t for the critical value

3-If the null and alternative hypotheses are H0: ? ? 100 and H1: ? > 100, the test is right-tailed

4-In hypothesis testing, we are trying to reject the alternative hypothesis

30-Autocorrelated errors are not usually a concern for regression models using cross-sectional data

33-The standard error of the sample proportion does not depend on the confidence level
