WebThe equation for the simple linear regression model is Sales = 27 + 5Adv - 0.25Adv(2). We are given that the advertising expenditure is $2 per capita. We can plug this value into the equation to calculate the predicted sales: Sales = 27 + 5(2) - 0.25(2)2. Sales = 27 + 10 - 0.5. Sales = 48 cents per/capita WebWe now have gotten rid of the interference, while postulating nothing different from the linear wave equation, and without worrying about "duality" or any such philosophy. The "projection postulate" turns out to follow naturally: obeying the wave eq, represents a situation in which, if the apparatus measures y again, it will get the same result.
