Question: - the mode - the sample variance - the coefficient of variation of that 121 students' weights ( 4 to 6 significant figures for each

- the mode - the sample variance - the coefficient of variation of that 121 students' weights ( 4 to 6 significant figures for each ) (e) Can an unbiased estimate of the population's range (i.e. the "sample range") be made? Why? Question 2 of 3 [20] You may use MS Excel to sort out the data [see Assignment_Data.xslx], you do not have to write down all the sorted numbers. The remaining procedure of computations however still need to answered by HAND on test pads By using the inclusive or the exclusive version (but do not mix!) of position measurement: (a) Calculate - the 81rd percentile - the 32th percentile - the percentile rank of 88.09 kg (b) Construct a Box and Whisker Plot for the data, showing all the necessary calculations for the Quartiles, Boundaries, etc. Question 3 of 3 [10] (a) Fill in all the three blacks below. You will need to go ONLINE to search for the answer The famous bell-shaped curve of the Standard Normal Distribution, comes from its P D. Function : @(x) . which has the formula Q(X) = (b) By using [GeoGebra Graphing Calculator] or [Calculator N+], generate a graph of p(x), covering . Your and axis need not be of the same scale
