6. 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 significance level of a=0.05 , is there enough evidence to support the researcher's claim? [Use Algebra first then Tech next] a. State the null and alternate hypotheses (write it mathematically) and write your claim. (2 points) b. Find the test statistic. (3 points) c. 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. (3 points) d. Find the pvalue and interpret its meaning. (2 points) e. Decide whether to reject or fail to reject the null using the p-value approach. (2 points) f. Make an interpretation of your decision in the context of the claim. (2 points)
