      • the p-value method • the critical value method . The p-value and critical value methods produce the same results. We will use the -pvalue method in this class. The p-value is the probability of obtaining a test statistic equal to or more extreme than the result obtained from the sample data, given that that the null hypothesis H 0 is true.

      p-value approach: Compare the probability of the evidence or more extreme evidence to occur when null hypothesis is true. If this probability is less than the level of significance of the test, α, then we reject the null hypothesis. (Reject H 0 if p-value < α) p-value = P(Z ≤−1.09 or Z ≥1.09)

      A P-value can also be reported more formally in terms of a fixed level α test. Here α is a number selected independently of the data, usually 0.05 or 0.01, more rarely 0.10. We reject the null hypothesis at level α if the P-value is smaller than α, otherwise we fail to reject the null hypothesis at level α.

      Hypothesis Testing In Statistics when testing claims we use an objective method called hypothesis testing Given a sample proportion, , and sample size, n, we can test claims about the population proportion, p. We call these claims hypotheses Our starting point, the status quo, is called the null hypothesis and the alternative claim is called the
