Document Summary

Instructions: please do all work in the space provided as much as possible. If you use additional paper, please write "see attached" and number your problems clearly. Correct answers without supporting work and/or explanation may not receive full credit. 1a) [6] you have test grades of 70, 86 and 82. Find your mean score (rounded to the nearest tenth) and your standard deviation. b) [6] you have test grades of 70, 86 and 82. What score do you need to get on the next test (rounded to the nearest tenth) to have an overall mean of 85? b) [6] you have test grades of 70, 86 and 82. Your final grade will be based on these three tests and a final exam weighted twice as much as a test. The researcher concludes that the highest number must be an outlier. b) a set of sample data is skewed toward the higher numbers.
