Null Hypothesis, Ha: The mean growth of Campylobacter jejuni is same when using five
different antibiotics. In five different samples.

As we have more than two samples therefore appropriate statistical test would be one way

The following are the important assumption of ANOVA in order to carry out the process of

• The samples are independent of each other.
• The samples are normally distributed.
• There is an equality of variances among groups.
As it can be seen that different antibiotic effect on growth are independent of each
or does not dependent on the any other antibiotic, therefore the first assumption is
met.
Normality Assumption
The null and alternative hy...
