+525 Suppose the length of an oarfish is normally distributed with a mean of 6.5 m and a standard deviation of 1.5 m.
Which group describes 16% of the oarfish population?
Select each correct answer.
+37146 Here is a graph of a standard bell curve: (ya just have to memorize the divisions)
6.5 m would be at the peak
Each line represents an oarfish 1.5 m shorter
The 16% total line is over to the left.....One line from the mean 6.5 - 1 line = 6.5-1.5 = 5 m
....so 16% are shorter than 5m
