Over the past several months, an adult patient has been treated for severe muscle spasms. This
condition is associated with a low average total calcium level. Recently, a random sample of 10
of the patient’s total calcium tests (measured in mg/dL) had mean x = 9.95 and standard
deviation s = 1.02. You may assume that the total calcium level in the patient’s blood has an
approximately
total calcium in this patient’s blood.

- The antibody production of 12 male red-winged blackbirds before and after receiving testosterone implants was compared. The units for antibody levels were natural log (10-3 optical density) per minute (In(mOD/min)). The mean change in antibody production was d = 0.056, and the standard deviation was sd = 0.225 If you were assigned the task of repeating this experiment, and wanted to ensure that you could detect a mean change of 0.02 units with a probability of 0.8, then what sample size would you use?
