determine p-value associated with the test statistic: get p-value from z- or t-test results on TI-84 or TI-Nspire . The . P-value (also called the . observed significance level) is a measure of the inconsistency between the hypothesized value for a population characteristic and the observed sample. The P-value is the probability, assuming that ...

Be able to calculate the test statistic, which is a z-value in this case. Be able to compute the P-value and be able to write out the probability statement for the P-value that involves the test statistic. Be able to determine whether or not the null hypothesis should be rejected. 6.4 Small-Sample Test for a Population Mean

Then choose how to display your results: Draw or Calculate. Draw will display the z distribution with the tail(s) shaded and it will display z and the P-value. Calculate will display the input values plus (, Sx (the sample standard deviation), z and the P-value. T-Test. Hypothesis testing using the t-distribution p. 146

power (of a test) Calculator Skills: ZInterval. Z-Test 11.1 Tests of Significance. What is a null hypothesis? What is an alternative hypothesis? In statistics, what is meant by the P-value? If a P-value is small, what do we conclude about the null hypothesis? If a P-value is large, what do we conclude about the null hypothesis?
