I have the following 2 samples

data 1 : 59.09 59.17 59.27 59.13 59.10 59.14 59.54 59.90

data 2: 59.06 59.40 59.00 59.12 59.01 59.25 59.23 59.564

And I need to check whether there is differentiation regarding the mean and the variance between the 2 data samples at significance level a=0.05

I think that the first thing I need to do is to check whether the samples come from a normal distribution in order to infer whether i should proceed using parametric or non marametric tests...

However using lillietest in matlab returned that both samples do not follow the normal distribution...

Any ideas on how should I proceed with checking the differentiation tests ? Should I perform ttest ? Or should I proceed by using something like Wilcoxon ? (p.s please confirm that that both data samples do not follow normal distribution...)
