Last Digit Analysis The dotplot below depicts the last digits of the weights of 153 males in Data Set 1 “Body Data.” Do those digits appear to be from a normally distributed population? If not, does the large sample size of n = 153 justify treating the values as if they were from a normal distribution? Can the sample be used to construct a 95% confidence interval estimate of σ for the population of all such digits?
