Question

In a random sample of​ males, it was found that 17 write with their left hands and 221 do not. In a random sample of​ females, it was found that 64 write with their left hands and 444 do not. Use a 0.05 significance level to test the claim that the rate of​ left-handedness among males is less than that among females

H0:p1 = p2

H1:P1<P2

and the Z was - 2.23 and P value was 0.013 and the hypothesis conclusion was

P value is Less than the significant level of a =0.05, so reject the null hypothesis. there is significant evidence to support the claim that the rate of​ left-handedness among males is less than that among females.

and..

the question is i need to find the "Claim by constructing and appropriate confidence interval."

The 90% confidence interval is?? i thought it was - 0.095 <(P1-P2)<-0.014

but the -0.095/-0.014 was not the answer? can you help me to find the confidence interval please?
