A financial advisor determines that the site is acceptable only if, on average, more than 300 automobiles pass the location per hour. If the advisor tests the hypotheses H0: μ ≤ 300 versus HA: μ > 300, μ stands for __________.A student believes that a certain 6-sided number cube, with the numbers 1 to 6, is unfair and is more likely to land with a 6 facing up. The student rolls the cube 100 times and lands with 6 facing up 20 times. The P-value for the test of the hypotheses, H_{0} / p = 0.17 and H_{a} / p > 0.17 is 0.19. What is the correct conclusion given a = 0.05 ? Because the P-value is less than a = 0.05 , the student should reject H_{0} Because the P-value is less than a = 0.05 , the student should reject H_{0} Because the P-value is greater than a = 0.05 , the student should reject H_{0} Because the P-value is greater than a = 0.05 , the student should fail to reject H_{0}
