Consider the following results for independent samples taken from two populations.

Sample 1 Sample 2

n1 = 400

n2 = 300

p1 = 0.53

p2 = 0.31

(a)

What is the point estimate of the difference between the two population proportions? (Use

p1 − p2.

)

(b)

Develop a 90% confidence interval for the difference between the two population proportions. (Use

p1 − p2.

Round your answer to four decimal places.)

  to  

(c)

Develop a 95% confidence interval for the difference between the two population proportions. (Use

p1 − p2.

Round your answer to four decimal places.)
