3) 4) After entering test scores from her statistics class, the instructor then calculates the mean and the median of all the scores and finds that the mean is significantly smaller than the median. What might this imply (a description) about the shape of the distribution of students' scores? (2 points) Students in an archaeology class kept a record of the length (in inches) of excavated bones for a class experiment. Their findings are given in the stem-and-leaf display below. (4 13 means 43 inches) 2 9 3 3 4 3 5 4 6 0 7 6 8 8 6 2 7 9 6 7 2 5 7 8 a) Show me the data and calculator functions you used to store and generate the answers to part b below (1 point). b) Find the mean, median, IQR, and standard deviation. (4 points) c) Describe the distribution using correct vocabulary and include the shape, center and spread. (4 points) d) Suppose the first data value was 9 inches instead of 29. For each statistic below indicate if it would increase, decrease, or stay about the same. (4 points) Median Mean IQR Standard Deviation 3) 4) After entering test scores from her statistics class, the instructor then calculates the mean and the median of all the scores and finds that the mean is significantly smaller than the median.
