Question
Multiple Choice: Please select the best answer and click "submit." IL-1beta is a protein released by cells under conditions of infection. Excessive release of IL-1beta can be very damaging and can lead to severe disease. In a typical experiment, the typical concentration of IL-1beta around stressed cells is 1000 plusminus 82 pg/ml. A researcher is testing drugs that can inhibit IL-1beta release. She tests two drugs, drug-1 and drug-2, for their effects on IL-1beta 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-1beta, while drug-2 yielded 782 pg/ml of IL-1beta. Is she going to continue studying either drug, and if so. which one? She will continue studying drug-1 but not drug-2. She will continue studying both drug-1 and drug-2. She will continue studying drug-2 but not drug-1. She will not study drug-2 or drug-1.Explanation / Answer
a)
Note that
z = (x-u)/sigma
Here, u = 1000, sigma = 82.
Hence, for drug 1,
z = (1427-1000)/82 = 5.207317073
We do not study this, as z is not less than -3.
For drug 2,
z = (782-1000)/82 = -2.658536585
Still, this is not less than -3, so she will not study it.
Hence,
OPTION D: SHE WILL NOT STUDY DRUG 2 OR DRUG 1. [ANSWER]
