A chamber of commerce executive OO feels that the commute time in his city is less and wants to publicize this. He randomly selects 26 commuters and finds the average is 24.4 minutes with a standard deviation of 5.3 minutes. At a = 0.10, is he correct? Assume the population is normally distributed. Part: 0 / 5 Part 1 of 5 (a) State the hypotheses and identify the claim. Ho: (Choose one) olo H1 : (Choose one) 0=0 This hypothesis test is a (Choose one) V test.

Assume the population is normally distributed. Part: 0 / 5 Part 1 of 5 V (a) State the hypotheses and identify the claim. Ho: (Choose one) H1 : (Choose one) 0=0 This hypothesis test is a (Choose one) test. X 5Female Physicians The percentage of physicians who are women is 27.9%. In a survey of physicians employed by a large university health system, 45 of 115 randomly selected physicians were women. Is there sufficient evidence at the 0.01 level of significance to conclude that the proportion of women physicians at the university health system exceeds 27.9%? OC Do not round intermediate steps.
