It is known 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.
I'd like help if someone can answer this for me before the end of the week. Thanks!If 4000 pygmy flying squirrels inhabit one area, how many would weight more than 49grams?
