b) We would reject the null hypothesis with an alpha of .05

c) The p-value is .018

Answer 1

1. If we examine an SPSS output where the two-tailed significance level is .018:

d) All of the above

Reasoning:

P value is 0.18 from SPSS

Now, if p value(0.018) > alpha(0.01), we fail to reject null hypothesis

If p value(0.018) <= alpha(0 .05), we reject the null hypothesis

2. The research and null hypotheses are always stated using Greek notation because the symbols of Greek notation refer to

- d) population parameters

Reasoning:

Greek letters refer to population attributes and Roman letters refer to sample attributes
