Answer #1

Here, mean = 12.6 , s.d = 1.2

For patient 1,

It is one half of a standard deviation above the mean. We know that, z score is the number of standard deviations above or below the mean. Hence, z score = 0.5

For patient 2,

z- score= -3.00

Hence, location description = 3 standard deviations below the mean

For patient 3,

It is one quarter of a standard deviation below the mean. Hence, z score = -0.25

We also know, z = (x - mean)/s.d

=> -0.25 = (x - 12.6)/1.2

=> x = 12.3 , i.e , Hb level = 12.3

For patient 4,

z- score= -2.00

Hence, location description = 2 standard deviations below the mean

For patient 5,

It is one standard deviation below the mean. z score = -1.00

z = (x - mean)/s.d

=> -1 = (x - 12.6)/1.2

=>x = 11.4 i.e , Hb level = 11.4
