Construct a stem-and-leaf plot to assess whether the data are from an approximately normal distribution. b. Find the values of Q1, Qy, and s for the sample data. c. Use the results from part b to assess the normality of the data. d. Generate a normal probability plot for the data, and use it to assess whether the data are approximately normal.
