A random sample of 16 new Ford Mustangs was selected from the assembly line to use to estimate the fuel economy of the model. Each vehicle was driven a total of 1,000 miles on a measured on a closed track for comparison. The number of gallons of fuel consumed for each vehicle was recorded. The average fuel consumption was found to be 45.7 gallons with a sample standard deviation of 1.9 gallons. The underlying distribution is symmetric. Construct the 99% condence interval around the mean fuel consumption. What amount of fuel consumption in this distance represents the upper bound of the 99% condence interval. Round your answer to the nearest whole gallon. Your Answer: Suppose you want to estimate the true proportion of students at UWG who support weekend classes. You obtain a random sample of n=78 student responses. From that sample, you find that 0.5 percent of UWG students are in favor of weekend classes. Construct the 95% confidence interval around the proportion in favor of weekend classes. What is the upper bound value of the 95% confidence interval for this proportion? Enter your upper-bound proportion value as a decimal rounded to the 3rd place to the right of the decimal, e.g., .234, not 23.4. Your Answer:In a normal distribution with a mean of 5 and a standard deviation of 1, what is the value of x at the 95th percentile (only 5% of values are greater than x)
