The data below represents the number of 50kg bags of maize produced by 100 small scale farmers in the 2019/21 farming season: 40 41 42 44 45 46 46 46 47 47 47 47 48 48 49 50 50 50 51 51 52 52 52 52 52 52 53 53 53 53 53 53 54 54 54 55 55 55 55 56 56 56 56 56 57 57 57 57 57 57 57 57 57 57 57 58 58 58 58 58 58 58 59 59 59 59 60 60 60 60 61 61 61 61 61 62 62 62 63 63 63 63 64 64 64 65 65 66 66 67 67 67 67 68 68 69 70 71 72 74 • Construct a stem-and -leaf plot and use it to determine the mode and the median for ungrouped data. • Construct an absolute frequency distribution and an absolute cumulative frequency distribution. • Construct a histogram, a frequency polygon, and use the histogram to estimate the mode and use the cumulative frequency polygon to estimate the median. •Determine the mean, the mode, the median, the variance, the standard deviation, and the coefficient of skewness for grouped data. Interpret correctly these numbers.
