Question

Suppose each of the following data sets is a simple random sample from some population. For each dataset, make a normal QQ plot. Look at the QQ plot and say whether the data are plausibly from a normalpopulation or whether they are evidence against a normal population. (Hint: In each case, to get somecontext for your decision, make a few QQ plots from samples of the same size that did come from a normalpopulation. Please do not include these context plots in your submission.)(a)data = c(7,13.2,8.1,8.2,6,9.5,9.4,8.7,9.8,10.9,8.4,7.4,8.4,10,9.7,8.6,12.4,10.7,11,9.4)(b)data = c(2.5,1.8,2.6,-1.9,1.6,2.6,1.4,0.9,1.2,2.3,-1.5,1.5,2.5,2.9,-0.1)(c)data = c(3.3,1.7,3.3,3.3,2.4,0.5,1.1,1.7,12,14.4,12.8,11.2,10.9,11.7,11.7,11.6)
