Pedroletti el al. (A-3) reported the maximal nitric oxide diffusion rate in a sample of 15 asthmatic schoolchildren and 15 controls as mean +, - standard error of the mean. For asthmatic children, they reported 3.5+- 0.4 nl/s (nanoliters per second) and for control subjects they reported 0.7+-.1 nl/s. For each group determine the following: What was the sample standard deviation? What is the 95 percent confidence interval for the mean maximal nitric diffusion rate of the population? What assumptions are necessary for the validity of the confidence interval you constructed? What is the 99 percent confidence interval for the mean maximal nitric diffusion rate of the population? What is the 90 percent confidence interval for the mean maximal nitric diffusion rate of the population?!
