Can anyone help me develop 90% confidence intervals including lower and upper limits for each of the follwing data:
the proportion of all people- 36%
the proportion of males -the percentage is 44%
the proportion of females- the percentage is 27%
the sample size is 80
I tried to do the all and the male intervals but Im very sure im wrong.
For the all I got -0.06896 and 0.107599
for the male I got -0.0668 and 0.11571
