The researcher would like to test the hypothesis that the average monthly wage for recent college graduates is less than $2000. A random sample of 19 recent college graduates averaged $1900 per month with a standard deviation of $350.50 per month. Test the researcher's claim using a = 0.10 that the average monthly wage of college graduates is less than $2000. Answer the following questions. a. Identify the claim and state the Ho and HI. b. Find the critical value. c. Calculate the test statistic. d. Make a decision to reject or fail to reject the Ho. (1 Mark) e. Interpret the decision in the context of the original claim. (1 Mark) Researchers suspect that 18% of all high school students smoke at least one pack of cigarettes a day. At St. John Highschool, a randomly selected sample of 300 students found that 50 students smoked at least one pack of cigarettes a day. Use a-0.05 to determine that the proportion of high school students who smoke at least one pack of cigarettes a day is less than 18%. Answer the following questions. f. Identify the claim and state the Ho and HI. g. Find the critical value. h. Calculate the test statistic. 1.Make a decision to reject or fail to reject the Ho.
