Question

IL-1ß is a protein released by cells under conditions of infection. Excessive release of IL-1ß can be very damaging and can lead to severe disease. In a typical experiment, the typical concentration of IL-1ß around stressed cells is 1000 ± 82 pg/ml. A researcher is testing drugs that can inhibit IL-1ß release. She tests two drugs, drug-1 and drug-2, for their effects on IL-1ß release. If the drugs have a z-score of -3, she will consider them promising for future study. In her experiment, stressed cells treated with drug-1 yielded 1427 pg/ml of IL-1ß, while drug-2 yielded 782 pg/ml of IL-1ß.

Answer 1

Is she going to continue studying either drug, and if so, which one?

A. She will not study drug-2 or drug-1.
B. She will continue studying both drug-1 and drug-2.
C. She will continue studying drug-2 but not drug-1.
D. She will continue studying drug-1 but not drug-2.

Answer 2

I think 1000 is your mean and 82 is your standard deviation. Use formula
\[Z= (X - Mean) \div Standard Deviation\]
Find the scores and compare
