A histogram titled "20 Busiest North American Airports" has a horizontal axis labeled "Total Passengers (Millions)" and a vertical axis labeled "Frequency" with values from 0 to 10. The histogram has 8 bars. Each bar is associated with a label and an approximate value as listed below. Frequency 10 O 0 7 02 8 3 30-39.9 20 Busiest North American Airports 40-49.9 50-59.9 Total Passengers (Millions) What is the lowest frequency value? 60-69.9 70-79.9 80-89.9 90-99.9 100-109.9

Briefly describe the distribution - shape, center, spread and possible outliers.

10) Data for various drivers is displayed below showing the relationship between their age and the furthest distance at which they can read a road sign. The table gives the maximum age, a, in years and the distance, d, in feet. The scatterplot shows the relationship between age and distance. a) A d age distance (years) (feet) 23 570 27 520 28 455 40 455 52 455 64 350 65 425 70 375 Sign Legibility Distance (feet) 600 500 400 300 T 15 25 35 45 55 65 Driver Age (years) Draw your line of best fit through the data points. 75 85 b) Pick two points on your regression line. IMPORTANT: These two points should be on your line and not data points from the table. Do not use the y intercept as a point, because the x axis does not start at zero. Write both coordinates of your points in the blank lines below. c) Use your two points from part b to find an equation for your line of best fit. Use the letters a and d in your equation. Do not use the letters x and y. If you end up with decimals in your…

Fill in extra columns for Years-Since-Squared and Years*Birds. Complete the table by adding rows for column totals and column averages. c) Calculate the linear regression for this model. e) Calculate the correlation coefficient for this model. f) Translate your linear regression so that the model is now Year vs. Number of birds. g) Add the model to your scatter plot. h) Compute the residual errors for your model. i) Plot your residual errors. j) Interpolate your model to find the number of birds in 1983 and 2001.
