The graph below displays the head volume, v, and brain weight, W of 134 men. Head volume is measured in cubic centimeters and brain weight is measured in grams. 1700 1600 1500 1400 Brain Weight (grams) 1300 1200 1100 1000 3000 3500 4000 4500 5000 Head Volume (cubic centimeters) The equation of the trend line is W = 450.3 + 0.2374v Use the equation of the trend line to predict the brain weight of a person who has a head volume of 3900 cubic centimeters. Include units. Do not round. ---Select--- Did you just interpolate or extrapolate? O interpolate O extrapolate One of the men included in the data set had a head volume of 3900 cubic centimeters and a brain weight of 1270 grams. Compare the weight of the real-life brain with the weight that you predicted in the last question. The real-life brain weighed grams ---Select--- | than what I predicted. Data Source: Source: R.J.

(Round your answer to the nearest whole number.) human cases If the number of human cases of West Nile virus reported in a year is 39, how many dead bird reports would we expect to be reported? (Round your answer to the nearest whole number.) dead birds reportedThe owner of a new car notices a strong negative correlation between the amount of tread remaining on his tires and the number of miles the car has been driven. The observed correlation is most likely due to: O cause and effect, since driving a car on road surfaces wears down the tire tread O the effect of a common underlying cause, such as the price of gas O a coincidence, since there is no logical explanation for the strong negative correlation O a mistake, since the correlation between miles driven and tire tread remaining is positive [-/1 Points] DETAILS MY NOTES ASK YOUR TEACHER Determine which pair of variables is positively correlated: O sales of mosquito spray and sales of winter coats O sales of mosquito spray and sales of bathing suits O sales of mosquito spray and sales of snow shovels O sales of mosquito spray and sales of dog food [-/1 Points] DETAILS MY NOTES ASK YOUR TEACHER Determine which pair of variables is negatively correlated. O the number of bites of a candy bar eaten and the amount of calories consumed the number of bites of a candy bar eaten and the amount of candy bar remaining O the number of bites of a candy bar eaten and cost of a gallon of milk O the number of bites of a candy bar eaten and the speed limit on the closest highway8.

The equation of the linear trend line for this relationship is given by: final score = 56 + 0.44*(midterm score) From the choices below, the best interpretation of the initial value (intercept) is: O A student who scored a 0 on the final is expected to score a 56 on the midterm O The final exam score is expected to increase by 0.44 points per point earned on the midterm. O A student who scored a 0 on the midterm is expected to score a 56 on the final O The midterm score is expected to increase by 0.44 points per point earned on the final. 9.

The equation of the linear trend line for this relationship is given by: final score = 42 + 0.58*(midterm score) From the choices below, the best interpretation of the growth rate (slope) is: O A student's midterm score increases by 0.58 points for every point earned on the final exam A student's final exam score increases by 0.58 points for every point earned on the midterm exam O A student who scored a 0 on the midterm is expected to score a 42 on the final O A student who scored a 0 on the final is expected to score a 42 on the midterm
