23
Answer is d. The null hypothesis is true yet type 1 error may occur.
(In NHST we always assume that Ho is true but there is still chance that type 1 error may occur)
24
Answer is b. Test statistics.
(We compute test statistics from sample data and then compare it with sampling distribution under null hypothesis)
25
Answer is d. Numerical; Categorical
(ANOVA is used when we have categorical independent variable and normally distributed dependent variable)
26
Answer is c. Numerical; either or both of numerical and categorical
(In multiple liner regression dependent variable is numerical and independed variable can be numerical or categorical or both)
