Using data from Exercises 5.2.3 and 5.2.4, use the Multiple Proportions applet to carry out a test of significance. Which of A–D is an approximate 2SD confidence interval? 

A. 0.082 to 0.218 

B. 0.116 to 0.184 

C. −0.0685 to 0.0685 

D. −0.068 to 0.068

Data from Exercises 5.2.3

Suppose you sample from two large populations and find sample proportions of p?₁ = 120/300 and p?₂ = 125/500. Suppose you are going to complete a test of significance using these proportions to see whether there is strong evidence that the population proportions differ. Which of the these are the appropriate hypotheses for this test?
