A researcher is conducting an MTT assay to assess cell viability. They seed 10,000 cells per well in a 96-well plate and treat them with a new drug. After 24 hours, the absorbance at 570 nm is measured for both treated and control (untreated) wells. The results are as follows: Control wells (untreated): Average absorbance = 1.2 AU Drug Treated wells: Average absorbance = 0.6 AU Calculate the percentage of viable cells in the treated wells compared to the

A researcher is planning an experiment and needs 5,000,000 cells. She has 14mL of cell suspension. Using trypan blue dye and a hemocytometer she counted 13, 11, 21, 20 clear cells in the four squares, she also counted 2, 7, 6, 4 blue cells respectively. What is the percentage of dead cells?

Assume the wattage output for 120V household electric motors follows an approximate normal distribution with a mean of 1900W and a standard deviation of 16.7W. a.) What percentage of motors will be able to produce at least 1886W?           b.) What output would be higher than 83% of all other motors?                   c.) Would a motor able to output 1920W be considered unusual?  Explain fully using probability.
