Determine the standardized test statistic
WebHere we see how to use the TI 83/84 to conduct hypothesis tests about proportions and means. The software will calculate the test statistic and the P-value for the test statistic. It does not give you the critical value. For tests about means, you can either input raw data via a list or simply enter the sample statistics.

WebX and X̅ are standardised slightly differently. In both cases, the denominator is the square root of the variance, like so: For X, Z = (X-μ) / σ. For X̅, Z = (X̅ - μ) / (σ / √n) This fits with what we know about the central limit theorem. For X, the variance is σ².

Using the p-value method, you could choose any appropriate significance level you want; you are not limited to using α = 0.05. But the table of critical values provided in this textbook assumes that we are using a significance level of 5%, α = 0.05. (If we wanted to use a different significance level than 5% with the critical value method, we would need …
