You want to know if smoking rates are different in your state (call this population 1) and your sister's state (call this population 2). Test this at the 5% level of significance. Suppose that random samples showed that 90 of 500 in your state were smoker's and 70 out of 500 in your sister's state were smokers. a. (3pts) State the null and alternative hypotheses. Is the alternative one-sided or two-sided? Smoking rates radom samples b. (6pts) Explicitly check any assumptions needed to apply the test. Show work.
