Why is the lab technician potentially a confounding variable in the study? What is the best explanation for the answer? Thanks! A researcher wanted to study the effects of a certain chemical on cell growth. The chemical was to be applied at twodifferent doses, high and low, to two different cell types, strain A and strain B. Each combination of dose and celltype was to be replicated ten times. To have consistency from one replicate to the next, the researcher decided to usefour lab technicians. One technician would be assigned the high dose with strain A. A second would be assigned thelow dose with strain A. A third would be assigned the high dose with strain B. A fourth would be assigned the lowdose with strain B. The assignment of lab technician to the replicates for a combination of dose and cell type wouldbe randomized. A statistician told the researcher that the design could be improved by controlling confoundingvariables. Which of the following is potentially a confounding variable in this study?(A) Chemical used(B) Lab technician(C) Dose(D) Cell type(E) Cell growth

First of all, we need to discuss about confounding variable. Confounding variable is a variable…

You need to use Stata to look up the dataset and its variables. Use Stata Companion Textbook. (Dataset: NES. Variables: spend8, [pw=nesw].) The NES dataset contains spend8, which records the number of government policy areas where respondents think spending should be increased. Scores range from 0 (the respondent does not want to increase spending on any of the policies) to 8 (the respondent wants to increase spending on all eight policies). The NES, of course, polls a random sample of U.S. adults. In this exercise you will analyze spend8 using the mean and lincom commands. You then will draw inferences about the population mean. (Remember to specify nesw as the probability weight.) The spend8 variable has a sample mean of ______. Make sure you use [pw=nesw] so your results are nationally representative. There is a probability of .95 that spend8’s true population mean falls between a score of ______ at the low end and a score of ______ at the high end. A student researcher…
