In year "2117", a research team in the BME-204 class designs a series of experiments for investigating the cardiac muscle cells, also known as cardiomyocytes from a newly-found mammal species (designated GZ07). The following questions are all based on their research findings. 1) Utilizing a micromechanical sensor, this team measures the individual c sample population measured is 100; the average cell w written as: 1.24x10-12± 0.16 x10-12 kg. The ell weight. The eight with standard deviation can be standard deviation of the sample mean is: A. 0.16 x10-14 kg B. 0.16 x1013 kg C. 0.16x10-1 kg D. 1.24 x10-14kg E. 1.24 x10 13 kg Page 2 of 7
Explanation / Answer
here as we know that std deviation of the sample mean =std deviation of population/(n)1/2
=0.16*10-12/(100)1/2 =0.16*10-13
therefore option B is correct
