... subscripts. Thus, the value of the r.v. X at the sample point s is X(s), and the set of all values of X, that is, the range of X, is usually denoted by X(S). Two kinds of r.v.’s emerge: discrete r.v.’s (or r.v.’s of the discrete type), and continuous r.v.’s (or r.v.’s of the continuous type). A r.v. ...

... The interpretation of a p-value of, say, 0.08 is: “If the null hypothesis is true, the probability of observing data as extreme or more extreme than what was observed in the sample is 0.08”. Remarks: • A p-value is not the probability that the null hypothesis is true. Be careful, this is a very comm ...
