b) Exhibit 2 shows the histogram and Exhibit 3 gives a table of summary statistics for the individual’s age of those included in the data. i) From Exhibit 2, with examples, provide three essential items that could improve the above chart. ii) From Exhibit 3, What is the median value and how do you obtain it. iii) From the answer you provided in part (ii) and based on Exhibit 2 and Exhibit 3, describe the shape of the distribution of this data. Give some intuitive explanation for why this data produces this shape. c) Use Exhibit 3 to interpret in context the central tendency of the smoker’s “Age”. d) i) Write down the formula for the sample standard deviation and using the sample variance from Exhibit 3 calculate the standard deviation value. Show all workings. ii) Other measures of the spread/dispersion of the data are the Range, Interquartile Range and Coefficient of Variation. From Exhibit 3, calculate the Range IQR, and CV
