Question: true or false when sample data occurs in pairs an...

Question details

True or False? when sample data occurs in pairs, an advantage of choosing a paired t-test is that it tends to increase the power of a test, as compared to treating each sample independently.

True or False? When testing the difference between two population proportions, it is necessary to use two samples with the same sample size.

True or False? If the sample proportions are p1=6/90 and p2=4/100, we can assume normality for the two sample proportions in a test comparing the two population proportions.

True or False? If the population variances are exactly equal for two populations, the F statistic based on two sample variances will be very close to zero.
