Upon examining the QQ plot of residuals, the financial analyst noticed that the points form an S-shaped curve. Did the residuals violate the normality assumption?Group of answer choicesYesNo

Which one of the following statements about QQ plots (Normal scores plots) and Normal Probability plots is FALSE?Group of answer choicesA QQ plot is a plot of the inverse cdf for the sample data.With regards to assessing normality, a  Normal Probability plot is conceptually the same as a QQ plot - however,  the axes are interchanged.A QQ plot is a plot of the sample quantiles against the corresponding quantiles of a standard normal distributionIf a sample is obtained from a Normal population, the QQ plot should be close to a straight line.A Normal Probability plot is a graph of the sample cdf with a (specifically) modified scale on the vertical axis.
