... The p-value above was calculated by a spreadsheet. If you are using tables, you will have a hard time coming up with a precise p-value, but you will be able to produce bounds. In our case, the t-score of 1.42118 lies (in the row for 32 degrees of freedom) between 1.694 (probability 0.05) and 1.309 ( ...

... • We have seen how to form confidence intervals for m when we have a normal distribution and known s, using the z distribution. • We now turn to the situation where s is unknown but the sample size is large or the sample population is normal. • Since s is unknown, we use s in its place. • However, w ...

... their widths vary, and the total area under the curve must be 1. The uniform distribution is not explicitly used very often in social science research, largely because very few phenomena in the social sciences follow such a distribution. In order for something to follow this distribution, values at ...

... Here, the notation, P(hh), is a shorthand for P(head on first toss, Head on second toss). Occurrences of a head the first time in no way influence the probability of a head the second time we flip a coin, as is obvious from looking at the sample space. Any of these four events are equally likely, pr ...
