. Given a set of data where mean = 37, SD = 6.2. show work  Calculate the z score for 31. Then Calculate the percentile score for 31. Next What percentage of the population would be expected to have a score greater than 41. With that info What score would be the 75th percentile for this dataset? If the SD increased to 6.7, what would the distribution look like and If the mean decreases to 31, how would this change the distribution?
