Mitchell is getting ready to take a baseball rules exam in order to becomne certified as a baseball umnpire in his local community. Past scores on the rules exam form a normal distribution with u = 80 and o = 6. Mitchell must score in the highest 25% of the distribution in order to become a certified umpire. Which minimum score does Mitchell need to obtain on the rules exam to become a certified umpire? OX= 76 O X- 84 OX= 86 OX-81

Jamie’s Intro to Biology professor tells the class that on the first exam, the mean score is a 70, but the median score is an 84.  What does this tell you about the skewness of the distribution?  What measures of center and spread would you use to describe this distribution?   a. The distribution is skewed left, so we should use the mean and the median to describe the distribution.   b. The distribution is skewed left, so we should use the median and the IQR to describe the distribution.   c. The distribution is skewed right, so we should use the median and the IQR to describe the distribution.   d. The distribution is symmetric, so we should use the standard deviation and the IQR to describe the distribution.   e. The distribution is skewed right, so we should use the mean and the IQR to describe the distribution.
