this file include 50 mothers.Please construct a 95% confidence interval for the difference in the population proportions of poverty among these two race groups. That is the 95% confidence interval for the population proportion of poverty among black mothers minus the population proportion of poverty among white mothers.race: race of mother (1=white, 2=black, 3=other). Please test whether the poverty proportion among black mothers is at least 5% more than that among white mothers at the level of significance of α = 0.05
could you please solve it in R programming and manual?

A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 318 people over the age of 55, 79 dream in black and white, and among 314 people under the age of 25, 13 dream in black and white. Use a 0.05 significance level to test the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25. Complete...
