Let $\vec{x}$ denote the following sample from an unknown population: (a) Graph the empirical cdf of $\vec{x}$. (b) Compute the plug-in estimates of the population mean and variance. (c) Compute the plug-in estimates of the population median and interquartile range. (d) Compute the ratio of the plug-in estimate of the interquartile range to the square root of the plug-in estimate of the variance.
