Explanation / Answer

The statistical software output for this problem is:

Two sample proportion summary confidence interval:
p1 : proportion of successes for population 1
p2 : proportion of successes for population 2
p1 - p2 : Difference in proportions

99% confidence interval results:

Hence,

99% confidence interval will be:

(-0.044, 0.033)
