(ii) Use the following commands
>qqplot(qexp(ppoints(length(x))), x)
>qqplot(qnorm(ppoints(length(x))), x)
>qqplot(qunif(ppoints(length(x))),x)
to discuss the distribution you may suggest for this data set.
(iii) Find the ve-number summary for this data set.
(iv) Find the interquartile range.
(v) Check for any possible outlier.
(vi) Find the mean and the standard deviation (i.e., x and s) for this data set. Check what percentage
of the data values fall within each of the following intervals.
(x ? s; x + s); (x ? 2s; x + 2s):
