Does this sound ok for my test? i couldn't figure out what to say for the last question. the tables show finn's history test scores and science test scores. history test scores 78 65 72 85 68 70 80 82 science test scores 78 45 80 88 80 78 62 x a) calculate the mean and the mean absolute deviation of finn's history test scores. give each answer correct to 2 decimal places. b) the score x represents the score of the science test finn has yet to take. if finn wants to have the same mean score in science as in history, what score must he achieve on his last science test? c) including the score of the last science test from part b), calculate the mean absolute deviation of the science test scores and compare it with the mean absolute deviation of the history test scores. what conclusion can be drawn about finn's test scores? my "the history test scores mean is 75. and the mad is 6.25. the science test score mean is 73, so in order to achieve a score of 75, x would equal 89. the mad for the science quiz scores, now including the 89, would be 10.75." i'm really bad at wording things, i could use some on the last question: "what conclusion can be drawn about finn's test scores? "
