A) Specify the competing hypotheses to determine if the proportion of white Americans initiating a contact outside their race is exactly 10 percentage points lower than that of black Americans.
B) Find the critical value(s) of the test.
C) Calculate the value of the test statistic.
D) Make a conclusion at the 5% significance level.
