In a Nanos Research survey of 1000 Canadian adults about how favourable they were toward the Alberta oil sands project, 19.5% were favourable and 25.6% were somewhat favourable. Of those who were favourable, 15.4% agreed that the oil sands project creates jobs, whereas the corresponding percentage for those who were somewhat favourable was 9.4%. Construct a 99% confidence interval for the difference between those who were favourable and those who were somewhat favourable as to whether the oil sands project creates jobs.
