Sketching required.
7. A car dealership would like to estimate the mean mpg of
its new model car with 90% confidence. The population is normally
distributed; however we are taking a sample of 25 cars with a
sample mean of 96.52 and a sample standard deviation of 10.70.
Calculate a 90% confidence interval for the population mean using
this sample data.

A car manufacturer is going to introduce a new model in the
market. The production process is so set that the mpg highway of
the new model has a population mean μ mpg with a population
standard deviation of 2.5 mpg. Based on 14 trials, a researcher
estimates the mean mpg (μ) with a confidence interval of (23.271,
25.469).
1. Does the researcher need any assumption to compute the
confidence interval for μ?
a) No, we do not require any...

A car company says that the mean gas mileage for its luxury
sedan is at least 21 miles per gallon (mpg). You believe the claim
is incorrect and find that a random sample of 7 cars has a mean gas
mileage of 19 mpg and a standard deviation of 3 mpg. At alpha
equals 0.025, test the company's claim. Assume the population is
normally distributed. Which sampling distribution should be used
and why? State the appropriate hypothesis to test. What...

We would like to estimate the mean salary for a given
population. In order to do that, we would like to take a sample. We
want a 95% confidence interval with a margin of error of 400. To
estimate the standard deviation of the population, we took a pilot
sample, the size of 30, and found the standard deviation of their
salaries to be 5000.
How many people do we have to ask to create our desired
confidence interval (total...
