Based on data from 1996-2006 from the Western Regional Climate Center, the average speed of winds in Honolulu, Hawaii is 10.6 mph, with standard deviation of 3.5 mph. Suppose we take a sample of 30 wind speeds. What is the probability that the mean wind speed exceeds 11.8 mph? That is find: P(X>11.8) a. 0.3669 or 36.69% b. 0.6331 or 63.31% c. 0.9699 or 96.99% d. 0.0301 or 3.01%
