... No! By simply reporting the sample mean, we are neglecting the fact that the amount of beer varies from bottle to bottle and that the value of the sample mean depends on the luck of the draw It is possible that a value as low as 11.75 is within the range of natural variability for the sample me ...

... Of course, if we have a large number of identical observations, we are almost sure (statisticians say that "with 95% certainty" or greater) that the test population is made up of such observations, regardless of whether our knowledge is stored in the form of numbers (measurable characteristics) or a ...

Finding the critical value(s) when doing hypothesis testing of population means using small samples is similar to the method we learned when we have large samples, but with some important differences. For one thing, rather than using the Excel function NORMSINV(probability) as we did with large samp ...
