In a sample of n= 19 lichen specimens, the researchers found the mean and standard deviation of the amount of the radioactive element, cesium-137, that was present to be 0.009 and 0.005 microcurie per milliliter, respectively. Suppose the researchers want to increase the sample size in order to estimate the mean u to within 0.002 microcurie per milliliter of its true value, using a 95% confidence interval. Complete parts a through c. a. What is the confidence level desired by the researchers? The confidence level is

Question
![**Sample Size and Estimation Accuracy in Radioactive Element Research**
In an experiment consisting of \( n = 19 \) lichen specimens, researchers determined the mean and standard deviation of the amount of the radioactive element Cesium-137 present in the samples, being 0.009 and 0.005 microcuries per milliliter, respectively. The researchers aim to increase the sample size in order to estimate the mean µ accurately to within 0.002 microcuries per milliliter of its true value, employing a 95% confidence interval.
