... Given: A company produces resistors by the thousands, and Mark is in charge of quality control. He picks 20 resistors at random as a sample, and calculates the sample mean x 8.240 k and the sample standard deviation S = 0.314 k. To do: Estimate the confidence interval of the population mean (as ...

(b) Unlike the last section, in the case that we sample from one population and then use a categorical variable to categorize observations as X’s or Y ’s, we will also analyze the data as sampling from ...

... That 95% of my sample is OK to do more tests That I am 95% confident that the confidence interval will contain the parameter being estimated That 5% of my sample is not ok That I am 95% sure that the population mean is 95. 8. Consider a binomial random variable where the number of trials is 12 and t ...
