Document Summary

Review question: examine the figure below that visualizes class data collected from week 7. Tutorial and answer the question below. (a) (b) (c: create a boxplot showing the blood-cholesterol levels of community members. Give the box a different colour than the threshold line. Density histograms of the original multitasking dataset (red) that we randomly sub- sampled from with sample sizes n=10 (green) and n=40 (blue) for 3 tutorial sessions (a-c). Vertical dotted lines show the means for the original data set (red), the n=10 samples (green) and the n=40 samples (blue): explain how the data in the figure above provides support for the central limit theorem. (1 mark) The remainder of this week"s report focuses on the cholesterol data set and the t-test: create a boxplot showing the blood-cholesterol levels of community members. Include a dashed horizontal line representing the threshold cholesterol value of 200 mg/dl. Label the axes appropriately, and give the figure a descriptive caption.
