5) For a hypothesis test the claim is < 4.7, so Ho: 4.7 and Hli < 4.7, giving a 1.8. A left-tailed test. A sample size of 15 is used to determine that = 3.6, s = 5% significance level is used. a) Sketch the appropriate distribution showing the tail(s) and their area, and b) c) d) show the location and value(s) of the critical value(s) determined from the appropriate distribution table (don't use a critical value obtained from a T 184 calculator except to check your work). Show the test statistic formula with the relevant numbers in place, and determine the test statistic value. Show where this value is located on the sketch of the distribution you made for part (a). State the proper conclusion of the test with regard to Ho and the original claim. Determine the p-value range using the appropriate distribution table and confirm the conclusion about Ho.
