Compute z-scores for all of these values. What's the z-score that comes closest to the mean of the distribution? What estimates define the extremes in the distribution (generally speaking, z = plusminus 2.00)?Explanation / Answer
Ans: z =(xi-mean)/std. dev
Closest to the mean ,z score =-0.03 (corresponding to 2.5)
z score corresponding to 7 is 2.1 >2,falls outside the limit of z=+2
there is no data below z=-2.
