5. The table below shows the height, in feet, of a rock thrown from the top of a building each second after it was thrown. Which model would fit this data best: linear, quadratic, or cubic? Use the model to write a best-fit equation, then estimate the height of the rock at 5 seconds. Time Height 0 250 1 280 2 284 249 202 3 4

1. Regression analysis was applied to return rates of sparrow hawk colonies. Regression analysis was used to study the relationship between return rate (x: % of birds that return to the colony in a given year) and immigration rate (y: % of new adults that join the colony per year). The following regression equation was obtained. ! = 31.9 – 0.34x Based on the above estimated regression equation, if the return rate were to decrease by 10% the rate of immigration to the colony would:  a. increase by 34%  b. increase by 3.4%  c. decrease by 0.34%  d. decrease by 3.4%ood alcohol by exactly 0.018/   2. In regression analysis, the variable that is being predicted is the  a. response, or dependent, variable  b. independent variable  c. intervening variable  d. is usually x   3. The correlation coefficient is used to determine:  a. A specific value of the y-variable given a specific value of the x-variable  b. A specific value of the x-variable given a specific value of the y-variable  c. The…

In the equation of a linear regression, Y = b1X + bo , if b1 = -4.7 which means %3D %3D O a. For each unit increase in x, y will decrease by 4.7. O b. For each unit increase in x, average of y will increase by 4.7 O c. For each unit increase in x, average of y will decrease by 4.7 O d. For each unit increase in x, y will increase by 4.7

In a study of the influence of financial institutions on bond interest rates in a certain country, quarterly data over a period of 12 years were analyzed. The postulated model was y¡ = Bo + B₁×₁¡ + B₂X2; + &¡, where y; is the change over the quarter in the bond interest rates, X₁₁ is the change over the quarter in bond purchases by financial institutions, and X2i is the change over the quarter in bond sales by financial institutions. The estimated regression coefficients are b₁ = 0.057 and b₂ = -0.033. Interpret these estimates. What is the correct interpretation of the coefficient estimates? Select the correct choice below and, if necessary, fill in the answer boxes within your choice. A. Each percent increase in the bond interest rates leads to a change in the estimated amount of bonds purchased by financial institutions by and a decrease in bond sales by financial institutions by. B. Each additional bond purchased by financial institutions leads to a change in the estimated bond…

In a simple regression problem, r and B O may have opposite signs. O must have the same sign. O must have opposite signs. O are equal.

The number of people living on farms in one country has declined steadily during the 20th century. Here are data on the farm population (in millions of persons) in 10 years.
