There's a claim that the average tuition fee in a private university for a year in the Philippines is greater than Php67500. You want to test this claim and you randomly sample 36 private universities and finds the mean to be Php70000. The population standard deviation is Php7500. Test the claim at 0.05 level of significance. a. State the null and alternative hypothesis. * Ho: u = 67500, H: u < 70000 Ha μ= 67500, H: μ > 67500 Ho: u = 67500, H:: u # 67500 H μ< 70000, Hi: μ > 67500 None of the above. b. Solve for the z-value. * O z = -2.575 z = 2.575 O z = 2 z = -2 None of the above
