(d) Use technology (for example, the \"Variance and Standard Deviation Applet,\" provided under Content > Course Resources > Free Web Applets in LEO, Excel, TI calculator) to: (1) nd the actual values (in two decimal places) for the variance (with its unit) and the standard deviation (with its unit) of your data set, considered as a sample. (2) If you mistakenly treated your sample as a population, what would be the impact of your mistake on calculated values for the variance and the standard deviation? Why? Briey explain. (e) Provide the ve-number summary. (t) Determine the lnterquartile Range (IQR). (g) Using your \"actual value\" for the standard deviation (STD) om Part (d)(l) above, determine what percentage of your data points would fall within one STD of the mean, i.e., within the interval (mean STD, mean + STD). Compare your answer with the Empirical Rule percentage. Briey explain the inconsistency, if any
