Please complete only highlited question #9

The table below presents the job tenure (years with the company) and annual salary (in $1,000s ) for ten nandomly selected employees holding similar occupations in a given mid-size corporation- 6. Complete the Totals for Years and Salary variables, then compute sample means Y and S. Y=12120/10=12S=60600/10=60 Complete the columns for the squared distance from the mean for Years and Salary, then compute the [population] variance and [population] standard deviation of each variable. (As before, use N, not N-1, Yes, this isn't a population, but we don't need to be picky yet.) Varr=1209=17.77Var5=8109=90StDevSey=17.77=4.216StDesS=909.487 7. List the observations (by name) that fall outside of the "expected variability" range that lies t/- 1 standard deviation from the mean (i.e. have values outside x+(S) of each varable. About what 9 of the data is this for this particular sample? Are "most" values in the range? For Years: 30% For Salary: 30% Most Values are in the range. 8. Compute the coefficient of variation for Years with the coenpany and the coefficient of vanation for Salary using your values above for the mean and standard deviation. Usmg. these vahes, Identify which job experaence of salary displays relativelu more variation: Coeficient of variation for Yeard with the company 35.1333. Coeficient of variation for Salary 15.8117 Job experience displays relatively more sariation thin salary. 9. If a standard Key Pertomance Indicator an this industry with respect to HR management was that salary ranges across employees should track closely to their varying experience with the furm how welf does this company seem to meet that goal? Do the longed-ierying erployes bave the highest salanes and yice-versa? Does varability in job tenune seem to correspond to smintarfy smed vanability in salary per the coefticient of variition or is enlary "compressed" such that you eam about the same in a nerrow range, regarile sof your loyalty to thie Whis isn tan essay question Jut concisely explain whar the statistig above sem to show) firm
