G b. (2 pt) Run the test from question a. What proportion of the sample are males? (Hint: click "Options" tab and choose "Normal approximation" for "Method".) c. (2 pt) What is the appropriate Z value for the test? d. (2 pt) What is the appropriate P-value for the test? e. (3 pt) Do you conclude that a minority of all Pitt graduate students are male?

On a certain portion of an experiment, a statistical test result yielded a p-value of 0.21. what can you conclude? 2(0.21) = 0.42 < 0.5; the test is not statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 21% of the time, so the test is not statistically significant. 0.21 > 0.05; the test is statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 79% of the time, so the test is not statistically significant. p = 1 - 0.21 = 0.79 > 0.05; the test is statistically significant.
