Unformatted text preview: n (1) Recall that the standard error is the typical distance between M and µ. Therefore, t tells us w! hether µ0 is a reasonable value for µ by telling us whether M – µ0 is a reasonable value for M – µ. For example, if t = 3, this means that M is three times as far from µ0 as you’d expect. Degrees of freedom for a basic t ­test. The probability distribution (or likelihood function) of a t statistic under the null hypothesis depends on its degrees of freedom. Therefore, you need to know how many degrees of freedom you have before you know which distribution to use. Degrees of freedom originates as a property of chi ­square distributions. Recall that the sam...
