35. Testing for Constant Difference To test the null hypothesis that the difference between two population proportions is equal to a nonzero constant

c, use the test statistic As long as n1 and n2 are both large, the sampling distribution of the test statistic z will be approximately the standard normal distribution. Refer to Exercise 12 and use a 0.05 significance level to test the claim that the virus leak rate for vinyl gloves is 50 percentage points greater than the virus leak rate for latex gloves.
