Question

Hello i need help answering these questions thank you.

"When the degrees of freedom are small(low), larger t-ratios are required to reject null." O True False QUESTION 12 Always, if Beta = 0.12, Power = 0.88. True False QUESTION 13 "When events are mutually exclusive, P (A and B) = 0." True False QUESTION 14 "If the same experimental subjects are given each of the two treatments, the experiment has a(n):" single sample design. independent subjects design one tail test design repeated measures design OOOO

Answer 1

1.

Since as degree of freedom increases we will get smaller critical value than small degree of freedom for same level of confidence hence critical values for small df is higher hence for rejecting H0 we need higher t critical value hence

TRUE

2.

Power =1-beta =1-0.12=0.88

Hence

TRUE
3.

mutually exclusive means there is no common element between two events hence

TRUE
4.

since here we are giving two treatments on the same subject hence we are repeating the same subject over two treatmetns hence

repeated measure design
