11 The GMAT (continued). Exercise 17.1 describes a study of the performance on the GMAT of college seniors in the Philippines. You stated the null and alternative hypotheses in Exercise 17.3. = 542. Enter this x, along with the other required information, into the P-Value of a Test of Significance applet. What is the P-value? Is this outcome statistically signifi- cant at the = 0.05 level? At the a = 0.01 level? (a) One sample of 250 students had mean GMAT score x (b) Another sample of 250 students had x = 532. Use the applet to find the P-value for this outcome. Is it statistically significant at the = At the a= 0.01 level? 0.05 level? Aingia (c) Explain briefly why these P-values tell us that one outcome is strong evidence against the null hypothesis and that the other outcome is not n p
