A medical researcher claims that less than 24% of adults in a certain country are smokers. In a random sample of 250 adults from that country, 18% say that they are smokers. At the significance level, is there enough evidence to support the researcher’s claim? State the null and alternate hypotheses (write it mathematically) and write your claim. Find the test statistic. Identify the Rejection region (critical region) and fail to reject region. Show this by drawing a curve and separate the rejection region from the fail to reject region using the critical value.
