// A car's miles-per-gallon (MPG) can be calculated with the following formula:
//
// MPG=Milesdriven/Gallonsofgasused

// Write a program that asks the user for the number of miles driven and the

Expert Solution
Below is the solution:
<!DOCTYPE html> <html> <body> <script>
//function to calculate the MPG
function calculateMPG(miles, gas) {
var MPG=miles/gas; //formua to calculate the MPG
(MPG=Milesdriven/Gallonsofgasused)
return MPG; //return
}
var milesDriven = prompt('How many miles have you driven? ');
//ask the user to enter the miles driven
var gasUsed = prompt('How much gas have you used driving that far?
') //ask the user to enter the gas used
alert('You car is getting ' + calculateMPG(milesDriven, gasUsed) + ' MPG.'); //call the function inside the aler to calculate the MPG

It is necessary for an automobile producer to estimate
the number of miles per gallon (mpg) achieved by its cars. Suppose
that the sample mean for a random sample of 5050 cars is 30.630.6
mpg and assume the standard deviation is 3.63.6 mpg. Now suppose
the car producer wants to test the hypothesis that μμ, the mean
number of miles per gallon, is 31.631.6 against the alternative
hypothesis that it is not 31.631.6. Conduct a test using a
significance level...

The manufacturer of a new compact car claims the miles per
gallon (mpg) for the gasoline consumption is mound-shaped and
symmetric with a mean of 27.4 mpg and a standard deviation of 12.3
mpg. If 30 such cars are tested, what is the probability the
average mpg achieved by these 30 cars will be greater than 28?
