nterpret a Confidence Interval: A center producing standardized exams for certifications wants to bette understand its Six-Sigma certification exam. They were only able to access a small sample of their scores, so they used the confidence interval formula with 98% confidence and obtained the values: 75 and 93. a)Interpret these values in the context of the problem. O The likelihood of obtaining a sample mean between 75 and 93 is approximately 98% We can be 98% confident that the population mean score is between 75 and 93. O There is a 98% chance that the population mean score is between 75 and 93. O There is a 98% chance that the sample mean score is between 75 and 93. b) The point estimate can be recovered even if you only know the endpoints of the confidence interval. What was the average score of the exams in their sample? (round to one decimal place) c) If they were to calculate a new confidence interval at 96% confidence, what (if anything) can be said about this confidence interval? O The 96% confidence interval would be more narrow. O It is impossible to tell O The 96% confidence interval would be wider

Gas mileage actually varies slightly with the driving speed of a car (as well as with highway vs. city driving). Suppose your car averages 29 miles per gallon on the highway if your average speed is 48 miles per hour, and it averages 26 miles per gallon on the highway if your average speed is 65 miles per hour. Answer parts (a) and (b) below. a. What is the driving time for a 2300-mile trip if you drive at an average speed of 48 miles per hour? What is the driving time at 65 miles per hour? The driving time at 48 miles per hour is hours. (Type an integer or decimal rounded to two decimal places as needed.) The driving time is at 65 miles per hour is (Round to two decimal places as needed.) b. Assume a gasoline price of $4.43 per gallon. What is the gasoline cost for a 2300-mile trip if you drive at an average speed of 48 miles per hour? What is the gasoline cost at 65 miles per hour? The gasoline cost at 48 miles per hour is $ (Round to two decimal places as needed.) hours. The…
