Modify Acron's model (Excel filed attached) so that development lasts for an extra year. Specifically, assume that development costs of $7.2 million and $2.1 million are incurred at the beginnings of years 1 and 2, and then the sales in the current model occur one year later, that is from year two until year 21. Again, calculate

Averages of several measurements are less variable than individual measurements. The true mass of the whiskey sample is 4.6 grams, or 4600 milligrams(mg). Antonio's measurements have the normal distribution with mean 4600 mg and standard deviation 10mg. In this case, the mean of his 3 measurements also has a normal distribution.
