Answer:

And for this case the confidence interval is given by:

Since the confidenc einterval not contains the value 0 we can conclude that we have significant difference between the two population proportion of interest 1% of significance given. So then we can't conclude that the two proportions are equal
Step-by-step explanation:
Let p1 and p2 the population proportions of interest and let
and
the estimators for the proportions we know that the confidence interval for the difference of proportions is given by this formula:

And for this case the confidence interval is given by:

Since the confidence interval not contains the value 0 we can conclude that we have significant difference between the two population proportion of interest 1% of significance given. So then we can't conclude that the two proportions are equal
