In a random sample of 95 Fusion owners, 45 of them were women. What is the 90% confidence interval estimating the proportion of all drivers who are women? 0 1) (0.33942 , 0.55795) 0 2) (-0.33942 , 0.55795) 0 3) (0.40303 , 0.53934) 0 4) (0.44205 , 0.61058) 0 5) (0.42246 , 0.52491 ) In the year 2000, the average car had a fuel economy of 24.1 MPG. You are curious as to whether the average in the present day is different from the historical value. What are the appropriate hypotheses for this test? 0 1) H0: [1 s 24.1 HA: p. > 24.1 0 2) H0: u at 24.1 HA: p. = 24.1 0 3) H0: p. > 24.1 HA: 1; s 24.1 0 4) H0: p. = 24.1 HA: u at 24.1 0 5) H0: p. a 24.1 HA: [.1
