e.   How would you describe Larry?

Answer 1

Ans:

a)Jerry is tallest,as z score is highest.

b)Larry weighs least,as z score is smallest.

c)Gary,as his height is average(as z score is zero) and weight is also on average approximately(as z=0.1,just above zero)

d)Harry's height is one standard deviation below the mean,but weight is 1.5 standard deviation above mean,so he is overweight(as compared to others)

e)Larry's height is 0.75 standard deviation above the mean,but weight is -0.90 standard deviation below the mean,so he is underweight(as compared to others)
