Give the numerical answers to the indicated number of decimals places.

a.) Construct the indicated confidence interval for the difference between population proportions p1-p2.

Assume that the samples are independent and that they have been randomly selected. Give answers correct to 4 decimal places.

x1=13,n1=36 and x2=32,n2=51;

Construct a 90% confidence interval for the difference between population proportions p1-p2.

b.) Construct the indicated confidence interval for the difference between the two population means. Assume that the two samples are independent simple random samples selected from normally distributed population. Do not assume that the population standard deviations are equal. Give answers correct to 1 decimal place. Independent samples from two different populations yield the following data. x1=358, x2=817, s1=46, s2=21. The sample size is 275 for both samples. Find the 80% confidence interval for u1-u2.

c.) Construct a confidence interval for ud, the mean of the differences d for the population of paired data. Assume that the population of paired difference is normally distributed. Give answers correct to 4 decimal places.
