9. (7 points) We have measurements of the lifetimes in minutes) of 6 sets of generic and 9 hs sets of brand-name AA batteries from a randomized experiment. Test a claim that the mean lifetime of generic batteries and the mean lifetime of brand-name batteries are different. (Do not forget to draw a conclusion.) sample (generic) n=6, mean = 206, standard deviation = 10 sample (brand-name) n=9, mean = 187, standard deviation = 14
