The Laboratory exercise asked for a test of the statistical significance of the mean of Sample 2. This led to a Z value of 1.96 and a p-value of 0.05. These calculated values are, entirely coincidentally, the same as the conventional critical value and significance level for the Z-test.

When performing a significance test…. Want to asses the strength of P-value, compare to .01, .05, .1 values of α. Chapter 12. SO much like Chapter 11. All the same concepts except we are including mean tests (Z and T), proportion tests (Z), and matched pairs test (L1-L2 = calculate using L3); Uses Chapter 9 also. Mean Problems:

use Minitab to test the statistical significance of the mean difference, verify the calculations and make a formal report on the result of the test. Division by n – 1 in the denominator of s eliminates the bias in s2 as an estimate of 2, but this does not apply to s; division by n – 1 reduces but does not eliminate the bias in s as an ...

Stat Test Menu: 1. z-test: NOT USED (for a mean when is known) 2. t-test: testing a mean from one sample or a matched pairs test. 3. 2-sampZtest: NOT USED (for means when is known) 4. 2-sampTtest: testing a difference of means from 2 samples. Note: always say “no” to pooling for this test. 5. 1-propZtest: testing a proportion from 1 sample
