(1 point) Buying your first car is an exciting time in any ones life. A worried father considers a lot of things when getting/helping/letting his child get that milestone ticket to freedom and possible destruction... Some factors one statistically savvy father considers are age and gender of child and how much money should he "invested" in this certainly doomed first transport. He conducts a survey and gathers the following data that he is sharing with you in the hopes that you can help him out. The data can be found in the Download .csv file. Use a = 0.10 for any statistical tests. Also, you can see the data laid out here for you. 9000 - GENDER 5000 - CAR_PRICE Female Male 3000 - 0- Less then 16 16 10 18 19 to 21 22 10 25 Older then 25 AGE (b) You wish to test the hypothesis that the Gender will effect the sale price of the first car. Of the options below, select the statistical hypothesis that will test this. O A. HO : Mlessthan16 # M16to18 # M19to21 F. .. HA : Mlessthan16 = M16to18 = M19to21 =. .. O B. Ho : Mlessthan16 = M16to18 = M19to21 =... HA : at least one ; is different O C. Ho : Hlessthan16 = M16to18 = M19to21 =... HA : Mlessthan16 # M16to18 # M19to21 ... O D. Ho : Amale = Mfemale HA : Mmale # HfemaleComplete the following two-way ANOVA table. Round to nearest integer for SS and MS and use at least two places after the decimal for the F values and at least three for the p-values. Source Degrees of Freedom Sum of Squares Mean Square F P-value Age Gender Interaction Error Total (c, i) Consider your statistical hypothesis in part (b). Compute the test statistic used to test Ho in part (b). Fcalc = (use two decimals in your answer) (c, ii) Find the P-value, using three decimals in your answer.
