Refer to the information in the exercise.

1. Construct three 95% confidence intervals.
   1. percent of all Asians who would welcome a White person into their families.
   2. percent of all Asians who would welcome a Hispanic/Latino into their families.
   3. percent of all Asians who would welcome a Black person into their families.
2. Even though the three point estimates are different, do any of the confidence intervals overlap? Which?
3. For any intervals that do overlap, in words, what does this imply about the significance of the differences in the true proportions?
4. For any intervals that do not overlap, in words, what does this imply about the significance of the differences in the true proportions?
