Sometimes professional basketball players aren't consistent in their performance game to game. Suppose that the standard deviation of the number of points scored by shooting guards in the NBA is 8.3. A random sample of 25 games played by Derrick Rose results in a sample standard deviation of 6.7 points. Assume that a normal probability plot indicates that the points scored are approcimately normally distributed. Is Derrick Rose more consistent than other shooting guards in the NBA at the a = 0.10 level of significance? The null and alternative hypothesis would be: : Ho: 8.3 Ho: 02-25 Ho: 0 6.7 H H
