1. A young adult German Shepherd can reach, on average, a top running speed of 30 mph with a standard deviation of 3.5 mph. Suppose that the top speeds of German Shepherds running is approximately normally distributed.

(a) Approximately what percentage of young adult German Shepherds can run between 23 mph and 37 mph. Explain how you know without using any tables.
(b) Find the 95th percentile of top running speed of young adult German Shepherds.

2. Give an example of a binomial distribution in the real world. You can make up the data and the parameters. Explain why it is a binomial distribution.

3.Find the corresponding area under the standard z-distribution for each of the following. (a) Area to the left of ? = 0.35

(b) Area between ?1 = 1.36 and ?2 = −0.93

In the 145 years of the running of the Kentucky Derby, the overall average speed of the horses under all track conditions has been 35.9025mph. Only nine years have been run under sloppy track conditions, including the last two years. Sloppy track conditions occur when the track is saturated with water with standing water visible. The speeds (mph) of the horses in these nine years were: 36.31, 36.23, 36.62, 36.16, 36.69, 36.27, 36.41, 35.89, and 35.27. Find the Geometric mean...
