Answer #1

90 % confidence interval of difference between purchase value of female and male is (-7.17 , 25.75)

since confidence interval contains 0

we can conclude that there is not significant difference in purchase value between male and female

similarly for 99% confidence level

(-16.26 , 34.83)

since confidence interval contains 0

we can conclude that there is not significant difference in purchase value between male and female
