Which statistical procedure would you use to test the null hypotheses that the programs are equally effective and to obtain a p-value?
(a)Paired t- test
(b)Chi Square Test
©One way Analysis of Variance
(d)2 sample t- test
(e)Fisher’s exact test
(f)Mann-Whitney (Wilcoxon rank sum) nonparametric test
