Can you please help with questions 7, 8, 9 and 10. Could you please label each clearly and show me the steps?

7) When an independent variable has more than 2 levels, why do we use a one-way ANOVA rather than multiple Hosts? 8) Ifwe have more than one independent variable, why do we do a two-way AN OVA rather than separate one-way ANOVAs? 9) 1n the state of Mississippi, 'i'0% of the population is white, 15% of the population is black, 10% of the population is Hispanic, and 5% of the population is Asian. 1n the school of medicine at Mississippi University (Ole' Miss) there are 200 students: 145 are white, 25 are black, 15 are Hispanic and 15 are Asian. Is the student body in the school of medicine representative of Mississippi as a whole? Set a at .05. SHOW ALL WORKING 10) Complete the following two-way AN OVA summary table for this 3 X 2 factorial design where N = 60. Determine whether the null hypothesis should he rejected or not for the A & B main effects and for the AB interaction. Finally, comment on which, if any, follow-up tests would be needed. Set alpha at .05. Source 35 a: MS F 10 30 AB 30 Error 70 Total 140
