Special Rounding Instructions For this exercise set, round all regression parameters to three decimal places, but round all other answers to two decimal places unless otherwise indicated. First Down The following table shows the probability P, as a percentage, of a college football team converting on fourth down when not goal to go versus the distance D, in yards, to the first down maker. 28 D = distance, in yards P = probability 1 70 2 60 3 53 4 46 5 41 6 37 7 34 8 32 a.Use exponential regression to model the data. b.Plot the data along with the exponential model. c.What probability does the model give of gaining a first down for fourth down and 10yards to go? Note: the actual probability is 28.
Present Value Present value is the amount of money that must be invested now at a given rate of interest to produce a given future value. For a one-year investment, the present value can be determined using PresentValue=FutureValue1+r, Where r is the yearly interest rate expressed as a decimal. Thus, if yearly interest rate is 8%, then 1+r=1.08. If an investment yields an yearly interest rate of 12% is available, what is the present value of an investment that will be worth 5000 at the end of 1 year? That is, how much must be invested today at 12% in order for the investment to have a value of 5000 at the end of a year?
Cable TV The following table shows the number C. in millions, of basic subscribers to cable TV in the indicated year These data are from the Statistical Abstract of the United States. Year 1975 1980 1985 1990 1995 2000 C 9.8 17.5 35.4 50.5 60.6 60.6 a. Use regression to find a logistic model for these data. b. By what annual percentage would you expect the number of cable subscribers to grow in the absence of limiting factors? c. The estimated number of subscribers in 2005 was 65.3million. What light does this shed on the model you found in part a?
