424 Corbly Hall deviation Medin- Mode - 73 2 Sore ? est a5

Solution

A z-score is a measure of the divergence of an individual experimental result from the most probable result, the mean. Z is expressed in terms of the number of standard deviations from the mean value. it is also known as z-value, standard score, or normal score. expression is as follow

mean= 67

median=66

mode=73

standard deviation =14

Calculated Z- score = (X- mean) / standard Deviation = (x-67)/14.

in this question x value not known so we write here general formula for calculate Z-score. for the given data set
