Your Best You cosmetics company's lipstick usually wears off in about two hours. Your Best You chemists have developed a new lipstick formula that they believe will last longer than their current product.

They get a new sample of women and run the test again.
They change their lipstick manufacturing to the new formula.
If the hypothesis test was set to an alpha of .05, they can say that the new product lasts 95% longer.
