Question 3 Not yet answered Marked out of 1.00 'F Flag question The Christchurch City Council is interested in determining if the proportion of commuters that use paid parking in the central city is less than 20% Select the hypotheses that the Christchurch City Council should use for this test. Select one: Q a. Ho: p : 0.20r Ha: p > 0.20 O b. H02p": 0.20, Ha:p\" 3.9. A random sample of 40 buses is taken and a P-value of 0.039 (to 3 dp) is calculated from the sample statistics. What conclusion may be drawn from this test? Use significance level a = 0.05. Select one: Q a. There is sufficient evidence that fuel efficiency has increased 0 b. There is evidence that fuel efficiency has not changed 0 c. There is insufficient evidence the fuel efficiency has increased 0 d. We have proved that fuel efficiency has increased Question 16 Not yet answered Marked out of 1400 \\V Flag question We have calculated a 90% confidence interval for u with the result (10, 15). What decision will we make if we test Ho: u : 16 against Ha: u 16 at o = 0.10? Select one: Q a. Do not reject Ho O b. Reject Ha O c. We cannot tell what our decision will be with the information given. 0 d. Reject HO 0 e. Do not accept Ha Question 7 Not yet answered Marked out of 100 \\'7 Flag question Given the null and alternative hypotheses below indicate the symbol for a sample statistic we might record for each simulated sample to create a randomisation distribution. Ho: [4: 67, Ha: u 0, Ha: M1 - M2 5 0 O b. Ho: M1 - M2 = 0, Ha: M1 - M2 > 0 O c. Ho: M1 - M2 = 0, Ha: M1 - M2 56 O c. Ho: M = 58, Ha: M > 58 O d. Ho: M = 58, Ha: M
