Imagine that we have a normal distribution of Exam scores for Psychology 210 with a mean of 75 and a standard deviation of 5. If I randomly drew a score of 90, would this be surprising? Explain your answer.

For the following line graph of quarterly percentage changes in five components of the CPI, which component had the largest decrease in the last quarter relative to the previous quarter?

A distribution with µ = 35 and σ = 8 is being standardized so that the new mean and standard deviation will be µ = 50 and σ = 10.  In the new, standardized, distribution your score is X = 45.  What was your score in the original distribution?

For the following box plot, D represents:

What is the mean for the following scores?  Scores: 1, 6, 7, 7, 14

If every X, or raw score, is transformed into a z-score the distribution will have:
