Question

a medical researcher is studying the relationship between pica and iro deficiency id ONAPCOAB01010000003b4b r is studying the relationship between pica and A medical r whom are women over the age of 60 who have been diagnosed with pica. He wants to mean hemoglobin level in women over the age of 60 is 12.6 gm/dl with a standard deviation of 1.2 iron deficiency. He measures the hemoglobin levels in five of his patients, all of Suppose the compare these levels to the population norms gm/di. The researcher compiles the following column of values is the patient's hemoglobin level (Hb level), the second column desenbes the location of that hemoglobin leve in the distribution of hemoglobin levels among women over the age of 60, and the third column contains the corresponding z-score of that patient's hemoglobin level. Fill in the missing values Hb Level (gm/dl) 2.0 10.2 Location Description Patient 1 Patient 2 Patient 3 Patient 4 Patient 5 one-half of a -2.00 one-quarter of a standard deviation below the mean -3.00 +1.00 9.0 one standard deviation above the mean 27:43 11:33 PM O Type here to search

Explanation / Answer

Z score is easy to calculate. It is (X-M)/SD, where X is the raw score, M is the mean and SD is the standard deviation.

To calculate the raw score, we can use z*SD+M.

I used excel to make my calculations faster.

Hb level Description z-score Patient 1 12 one half of the SD below the mean -0.5 Patient 2 10.2 two SD below the mean -2 Patient 3 12.3 one quarter of SD below the mean -0.25 Patient 4 9 three SD below the mean -3 Patient 5 13.8 one SD above the mean 1
