A random sample of six cars from a particular model year had the following fuel consumption figures (in miles per gallon). Find the 80% confidence interval for the true mean fuel consumption for cars of this model year. Left endpoint=? Right endpoint=?
Sample data:
19
20.9
19.8
18.9
18.9
18.1
Hence 80% confidence interval is ( 18.6854 , 19.8480 )
Hope this will help you. Thank you :)

The fuel consumption, in miles per gallon, of all cars of a particular model has a mean of 90 and a standard deviation of 12. The population distribution can be assumed to be normal. A random sample of these cars is taken. (a) What is the sampling distribution of the sample means? (b) Find the probability that sample mean fuel consumption will be fewer than 75 miles per gallon if: i. a sample of 1 observation is taken. ii. a...
17 randomly selected cars are driven for a tank and is found that the sample mean fuel consumption is 9.4 l/100k with a sample standard deviation of s = .437. suppose the manufactuer wishes to construct a confidence interval for mu the true mean fuel consumption for the model under these consitions what is the margin of error of a 95% confidence interval for mu what is the margin of error of a 90% confidence interval for mu
Fach year the US Environmental Protection Agency (EPA) releases fuel economy data on cars manufactured in that year. Below are summary statistics on fuel efficiency (in miles/gallon) from a random sample of cars with manual transmissions and a random sample of cars with automatic transmissions manufactured in 2012. Assume that conditions for inference are satisfied City MPG Automatic Manual 16.12 19.85 3.58 4.51 Mean SD automatic manual City MPG (a) Compute the standard error (SE) of the difference of the...
question 9 Question 9 View Policies Current Attempt in Progress A random sample of n = 16 mid-sized cars tested for fuel consumption gave a mean of x = 28.90 miles per gallon with a standard deviation of s = 2.11 miles per gallon. Assuming that the miles per gallon given by all mid-sized cars have a normal distribution, find a 99% confidence interval for the population mean, . Round your answers to two decimal places. SHS i
7 A car manufacturer is interested in estimating the true mean fuel consumption in real-world city driving for one of its new models. 10 new randomly selected cars are driven for a tank, and it is found that the sample mean fuel consumption is 9.4 l/100k, with a sample standard deviation of s = 0.343. Suppose the manufacturer wishes to construct a confidence interval for mu, the true mean fuel consumption for this model under these conditions. a) What is...
