Testing the plausibility of a suggested population mean (via a z-test). [This is what we’ve just done]. • Are the means from two samples sufficiently d ...

... a neutral response to the package design. ii) Sometimes, the responses to a question are given in terms of names (nominal data), which cannot be treated as numbers. For example, if we ask young graduates “in which part of the country would you like to take up a job and live”, the replies could be no ...

... Is n large? If it is, then the CLT verifies that the distribution of x-bar is approximately normal. If n is not large, then we need to examine the data. If the histogram or boxplot of the data is symmetric with no outliers (or the normal probability plot is linear), it is plausible to assume tha ...
