A random poll of 100 males and 100 females who were likely to vote in an upcoming election found that 55% of the males and 25% of the females supported candidate Johnson. Call the population of males “Population 1” and the population of females “Population 2” while working these problems.

With 90% and 95% confidence levels, what are the confidence intervals for the difference in the percentage of males and females favouring Johnson among all likely voters?
