Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability related to the Z score.
On the sixth day of Statistics, my teacher gave to me, six geese-a-laying. The eggs they were a-laying were normally distributed and had a mean of 7cm and standard deviation of 2cm. What is the probability that if you randomly select one egg from each of the six geese, the mean of all six will be less than 6 cm?
