Hello everyone. I would like to ask about help with statistic - again ;(
I try do something but I am not sure. Thank you for help.
1. Determine if average prices for female shoes is less than average prices for male shoes. Compare the result with part 1 question 1. Does the result confirm your previous findings? (Follow the hypothesis testing steps, 0.05 level of significance, assuming "none equal variances" of populations).
I THINK THAT HYPOTHESIS CAN BE FRAMED AS:
We have lower tail lest
Reject H0 if calculate t < -t n1+n2-2
From table calculate t =0.753 ( this data I have from excel analysis data )
Critical t =1.666
no reject H0
and I thing that graph look like that
I have also another one but I do not know how framed hypothesis
q2 Determine if there is a difference in shoes prices in different countries( we have 3 ) (Follow the hypothesis testing steps, 0.05 level of significance). everyone, I need again help with statistic :(
please show me how wrote hypothesis for q2
Thank you for help
