Explanation / Answer

a) Ho:usludge=uspring=unotill

H1 :Atleast one of the means is different

option b satisfies condtion

b) Requirements of a One-Way ANOVA Test

1. There are k simple random samples from k populations.

2. The k samples are independent of each other; that is, the subjects in one group cannot be related in any way to subjects in a second group.

3. The populations are normally distributed.

4. The populations have the same variance; that is, each treatment group has population variance

for above conditions
