A marine biologist has determined that the weight of a full weight of 2000pounds and a standard deviation of 500 pounds. Determine the probability that the average weight of the next five sharks captured will be less than 2100lbs.

Answer 1

Z = (score-mean)/SD

Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion from the Z score. This is the probability for one shark.

The probability for all events is found by multiplying the probabilities of the individual events.
