It is known (only in my head, this a math question) that pygmy flying squirrels normally have a weight distributed with a mean of 40 grams and that the standard deviation from this mean is 3.5g. If 4000 pygmy flying squirrels inhabit one area, how many would weight more than 49grams?
This is a question from Wajas, and yes, Estu does allow it.Help! Flying Squirrel Math!?
20
49 g is 2.57 standard deviation from the mean. This translates to .9949 of the population with a weith that is lower than this limit, leaving .0051 above it. .0051 of 4000 is 20 individuals.Help! Flying Squirrel Math!?
use the equation:
y= mx + b
