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:

H0:m1 ≥m2

Ha:m1 <m2

H0:m1-m2 ≥0

Ha:m1 m2<0

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

0.753<-1.66

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
