To be diagnosed with pica, these cravings need to last longer than a month and be developmentally inappropriate. Pica is seen in all ages, but more commonly among pregnant women, small children, and those with developmental disabilities. Pica can lead to serious medical problems, particularly when the substance ingested can lead to poisoning (such as lead poisoning from paint chips), parasites (for example, from soil), or intestinal blockages. [Source: American Psychiatric Association. Diagnostic and Statistical Manual of Mental Disorders. 4th ed. Text rev. (Washington, DC: American Psychiatric Association, 2000).] A medical researcher is studying the relationship between pica and iron deficiency. She measures the hemoglobin levels in five of her patients, all of whom are adult males who have been diagnosed with pica. She wants to compare these levels to the population norms. Suppose the mearn hemoglobin level in adult males is 15.9 gm/di with a standard deviation of 1.2 gm/d. The researcher compiles the following table, where the first column of values is the patient's hemoglobin level (Hb level), the second column descrbes the location of that hemoglobin level in the distribution of hemoglobin levels among adult males, and the third column contains the corresponding z score of that patient's hemoglobin level.

Explanation / Answer

Patient - 1: z score is two standard deviation below the mean so z - score = -2.00

Patient - 2: z score is +0.50 so z score is one-half of standard deviation above the mean.

Patient - 3: Hb level = 15.9 + 0.25*1.2 = 16.2

z score = +0.25

Patient - 4: z score is three standard deviation below the mean.

Patient - 5: Hb level = 15.9 - 1*1.2 = 14.7
