A consumer group compared the life span of two types of razor blades: the Up&Up generic Target brand blade and name-brand Gillette blade. Two independent samples were randomly selected - one sample of ten Up&Up blades and a different sample of ten Gillette blades. The number of shaves obtained before a blade became too dull to provide a close shave was recorded for each blade. Life Span of Razor Blades - # of Close Shaves Up&Up Razor Gillette Razor Blade Blade 08 6,7,99 = 1, 8103, 5, 6,9 1, 8110, 2, 3, 6 9122 6130 103 103 close shaves (a) Compare the distributions using their SOCS. Show the calculations leading to your outlier conclusion. (b) Which razor should be recommended to consumers wanting to purchase the better razor? Use
