Goodness of Fit Test. 1. A player in a crap game suspects that one of the dice used in the game is loaded. A loaded die is one where all the possibilities are not equally likely. The player throws the die 400 times and records the outcome with the following result. 4. 76 76 62 62 57 67 Test whether the die is loaded at a = 0.01 level of significance. Teat of Independence A survey of randomly selected Americans 18 years of age and older were asked whether they 2. supported the limited use of marijuana when prescribed by a physician to relieve pain and suffering. The results were as follows. Age 50 or older 30-49 years old 18-29 years old Opinion 258 313 172 For 119 103 52 Against Test whether age and opinion are independent at a = 0.05 level of significance. Anova Test. 3. Suppose the National Transportation Safety Board (NTSB) wants to examine the safety of compact cars, midsize cars, and full-size cars. It collects a sample of three for each of the treatments (cars types). Using the hypothetical data provided below, test whether the mean pressure applied to the driver's head during a crash test is equal for each types of car.
