... A runner ran the 800 meter “dash” in 145 seconds. At the meet, the average time was 137.6 seconds, with a standard deviation of 4.3 seconds. Express the runner’s time in units of standard deviation. How did the runner do compared to the other contestants. In the same race as described in question 2, ...

... which you would like to make conclusions. A sample is a smaller group of items selected from the population and is the group on which you calculate statistics and use inference to make conclusions about the population. The method of selecting items to be in your sample is important because inference ...

... tested statistically. Statistical hypotheses deal with the behavior of observable random variables. These are hypotheses that are testable by observing some set of random variables. They are usually related to the distribution(s) of observed random variables. For example if we have observed two sets ...

Consider these practical guidelines for inference on a single mean: – If the sample size is < 15, use the t ...
