The following regression model has been proposed to predict sales at a computer store. Y hat = 50-3(x1)+20(x2)+10(x3) where x1 = competitors previous day's sales (in $1,000s) and x2 = population within 1 mile (in 1,000s).
Suppose we take 25 i.i.d observations from normal distribution with population standard deviation known to be 30. Given the same population standard deviation, how many observations need to be collected to have a half width of 95% CI less than 10?
