As a​ follow-up to a report on gas​ consumption, a consumer group conducted a study of SUV owners to estimate the mean mileage for their vehicles. A simple random sample of 83 SUV owners was​ selected, and the owners were asked to report their highway mileage. The results that were summarized from the sample data were x=18.6 mpg and s=5.7 mpg. Based on these sample​ data, compute and interpret a 95% confidence interval estimate for the mean highway mileage for SUVs. The 95​% confidence interval is ___mpg  ------- ____mpg. ​(Round to one decimal place as needed. Use ascending​ order.) One can conclude_________
