Inference w/ Intervals (4)
In a random sample of Toyota car owners, 83 out of 112 said they were satisfied with the Toyota front-wheel drive, while in a similar survey of Subaru owners, 76 out of 81 said they were satisfied with the Subaru four-wheel drive.  A 90% confidence interval estimate for the difference in proportions between Toyota & Subaru car owners who are satisfied with their drive systems is reported to be -0.197 ± 0.081.  Which is a proper conclusion?
A) The interval is invalid because probabilities cannot be negative.
B) We are 90% confident that the difference in proportions between Toyota and Subaru car owners who are satisfied with their drive systems is between -0.278 and -0.116.
C) The interval is invalid because it does not contain zero.
D) Subaru owners are approximately 19.7% more satisfied with their drive systems than are Toyota owners.
