Answer 1

Solution-

Which hypothesis test do we use when comparing more than two samples of normal data?

- d) ANOVA

Option d) ANOVA is correct.

◆Assumptions for ANOVA

To use the ANOVA test we made the following assumptions:

• Each group sample is drawn from a normally distributed population
• All populations have a common variance
• All samples are drawn independently of each other
• Within each sample, the observations are sampled randomly and independently of each other.

If we have two independent samples from normal data then we can use t-test or Z-test.

But in case of more than two samples we can use ANOVA test for normal data.
