Cannabis sold in dispensaries is made up of several important elements, the most important being THC. Several firms sell their product through the dispensaries. You are given the following information about the amount of THC (in milligrams) in a gram of Cannabis. The Consumer Advocates of Canada decided to collect samples as part of their consumer advisory newsletter. In a sample of 21 from Firm ACD, the mean amount of THC was 19.35 milligrams with a variance of 0.0058. The sample of Firm MFM was 27 with a mean of 19.47 and a variance of 0.0562. The sample from Firm GH had a mean of 19.16 and a variance of 0.0330 for 19 purchases. a) Test to determine whether there is sufficient evidence that GH's product is within 1 milligram of 19.16. Use an Alpha of 1%. b) Consumer Advocates also wanted to determine whether MFM's product had a higher-level of consistency in relation to THC then that of GH's product. Use an Alpha of 5%. c) Consumer Advocates wanted to observe whether all firms were offering the same level of THC in their products or whether there was a difference. Calculate the appropriate Test Statistic value for this test (do not complete the full hypothesis test)
