Multiple Choice
A chemist is interested in comparing four different catalysts by measuring reaction times.Each catalyst is tested five times,with each experiment randomly assigned one of the four catalysts.Calculate
,
And the F-ratio.Can you reject
Using α = 0.05? The ANOVA table is listed below.
A)
= 2.328;
=4.958;F-Ratio = 0.470;No,do not reject
Using α = 0.05.
B)
= 3.103;
=4.666;F-Ratio = 0.665;No,do not reject
Using α = 0.05.
C)
= 3.103;
=4.175;F-Ratio = 0.743;No,do not reject
Using α = 0.05.
D)
= 2.328;
=4.175;F-Ratio = 0.558;Yes,reject
Using α = 0.05.
E)
= 3.103;
=4.958;F-Ratio = 0.626;No,do not reject
Using α = 0.05.
