Most statistical software packages have routines for generating values of variables having specified distribution.use your statistical software to generate 30 observation from the N(25,8) distribution.compute the mean and standard deviation X and s of the 30 values you obtain. how close are x and s to the 30 values you obtain.how close arex and s to the m and of the distribution from which the observation were drawn? repeat 19 more times the process of generating 30 observation from the N(25,8) distribution and recording xbar and s.make a stemplot of the 20 values of x and another stemplot of the 20 values of s. make normal quantile plots of bith sets of data,briefly describe each of these distributions,are they symetric or skewed? are they roughly normal? where are their centres? (the distributions of measures like x and s when repeated sets of observations are made from the same theoretical distribution will be very important in later chapters.)
