A firm is faced with the attractive situation in which it can be obtain immediate delivery of item it stocks for retail sale. The firm has, therefore, not bothered to order the item in any systematic way. However, recently profits have been squeezed due to increasing pressures, and the firm has retained a management consultant

Why do you think different polls got such a wide range of estimates of Bush's lead in the polls, ranging from a 12% lead to a 4% lead? What sampling techniques would you use to get the most accurate estimate of which candidate would win on election day?
Prior to the November, 2000 presidential election George W. Bush had a comfortable lead in the polls. But on election day Bush ended up losing the popular vote by a small margin (although winning the electoral vote). Read the following article below written before the election: Larry Kudlow (2000) The Weak-End of Polling,
A breeding group of beavers introduced into a protected area. After t years the number of beavers in the area is modeled by the function N(t) = _____54__________ 0.35+0.68t (note: this t by 0.68 should be an exponent,couldn't make one here.) 1. How many beavers were initially introduced? 2. Estimate

When a ball is thrown up into the air, it makes the shape of a parabola. The equation S= -10t^2 + v*t + k gives the height of the ball at any time, t in seconds, where "v" is the initial velocity (speed) in meters/sec and "k" is the initial height in meters (as if you were on top of a tower or building). Make up a scenario wh
