Consider the following stem-and-leaf display of the time (in hours) that it takes to courier 19 blood samples to the laboratory. Stem-and-Leaf display (Leaf unit = 1) 0 2 4 5 8 1 0 4 4 5 8 2 5 5 6 30 2 7 4 1 2 3 8 Given: : Σ12, 1, = 439, Σ2, = 13967, Σ? (Σ", α.) Σ”, ) - 192721, Σ2, (α; - ) = 0 and Σ2, (α; - )2 = 3823.79
Calculate the following descriptive statistics: . Two measures of location namely: The mean, T = Round your answer to 3 decimal places. o o The median, me = Round your answer to 1 decimal place. o Two measures of spread namely: The range, r = Round your answer to the nearest integer. The standard deviation, s = Round your answer to 3 decimal places. O b) A box-plot is a graphical representation of the data that helps us to get an idea of the location, the spread and also the shape of the data Given: The first quartile is Q1 = 10. . hours. The value of the third quartile, is Q3 Round your answer to 1 decimal place. By making use of the box-plot approach, a value may be regarded as an outlier if it is more than Round your answer to 2 decimal places.
