// 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 
// gallons of gas used. It should then call a function to calculate and return 
// the car's MPG and display the result.

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...
