As part of a class project, a university student surveyed students in the cafeteria to look for a relationship between the students' eye color and hair color. the table contains the survey results. match the descriptions with the correct values.

Ianswered a similar question and it had this table: eye color  hair color :         blue     gray     green     brown       marginal totalblond                   42             5           21           10                   78red                     12       22           19             12                 65brown                 22           5           12             34                   73black                     9           3           11           64                   87marginal total:   85           35             63       120                 303based on that table, out of 303 people interviewed,85/303 = 0.28 ; 0.28 x 100% = 28% are blue eyed35/303 = 0.12 ; 0.12 x 100% = 12% are gray eyed63/303 = 0.20 ; 0.20 x 100% = 20% are green eyed120/303 = 0.40 ; 0.40 x 100% = 40% are brown eyed  78/303 = 0.26 ; 0.26 x 100% = 26% are blond65/303 = 0.21 ; 0.21 x 100% = 21% are red head73/303 = 0.24 ; 0.24 x 100% = 24% are brown haired87/303 = 0.29 ; 0.29 x 100% = 29% are black hairedhere are the relative frequency of each hair and eye color combinationeye color  hair color :   blue                     gray                   green             brown       blond           42/303=  0.14     5/303= 0.02    21/303=  0.07   10/303= 0.03            red               12/303=  0.04     22/303= 0.07  19/303= 0.06  12/303= 0.04          brown           22/303=  0.07     5/303=  0.02   12/303= 0.04  34/303= 0.11            black             9/303=  0.03       3/303= 0.01  11/303= 0.04    64/303= 0.21    when you add up all these decimals, you will have a sum of 1. each decimal represent the portion of people with a specific combination of hair and eye color that are part of the 303 people surveyed.                if this is your missing question: the percentage of the sample population with brown eyes and black hair is larger than the percentage of the sample population with blue eyes and black hair by points.my answer:   brown eyes -  black hair: 64/303 = 0.21 or 21%blue eyes - black hair: 9/303 = 0.03 or 3%21% - 3% = 18%the percentage of the sample population with brown eyes and black hair is larger than the percentage of the sample population with blue eyes and black hair by 18 (eighteen)  percentage points.
