Explanation / Answer

e)

Hypothesis :

H0 : There is no difference in the mean values across the groups

H1 : There is a statistical difference in the mean values across the groups, atleast for 2 groups.

if the calculated p value is less than the assumed signficance level(0.05) , then we reject the null hypothesis else we fail to reject the null hypothesis

here the p value is 0.053 , hence the p value is slightly more than alpha = 0.05 , hence we fail to reject the null hypothesis and conclude that There is no difference in the mean values across the groups
