hat a random sample of 60 accounting graduates at a large university who received job offers resulted in a mean offer of $49,800 and a standard deviation of $3,100. What is the observed significance level?

The diagonal is the hypotenuse of a right triangle with the sides of the square as legs. By Pythagoras (s = side) s^2 + s^2 = 15^2 2s^2 = 225 s^2 = 112.5 s = sqrt(112.5) s = 10.6 cm (to the nearest tenth)
