Rick is a school principal, and he is trying to decide if there is a relationship between conduct infractions
and the number of students present at school during the day when infractions occur. How should he set
up a scatterplot to help him see if there is a relationship?
O plot the number of infractions on the y-axis and the number of students present on the x-axis
O plot the number of infractions on the y-axis and the day of the week on the x-axis
O plot the number of infractions on the x-axis and the number of students present on the y-axis
O plot the number of infractions on the x-axis and the day of the week on the y-axis
In the United States, it is illegal to drive with a blood
alcohol concentration of 0.08 or higher. (A blood alcohol
concentration of 0.08 indicates 0.08% alcohol in the blood.)
The scatter plot shows the relationship between the number
of one-ounce beers consumed per hour by a 200-pound
person and that person's corresponding blood alcohol
concentration. Also shown is a line that passes through or
near the data points.

a. Use the two points whose coordinates are shown by the
voice balloons to find the point-slope form of the equation
of the line that models the blood alcohol concentration of
a 200-pound person, y, who consumes x one-ounce beers
per hour.
b. Write the equation from part (a) in slope-intercept form.
Use function notation.
c. Use the linear function to predict…
Data was collected on the number of pairs of shoes people own and the number of miles they walk per week. r2=0.38. Then 38% of the variation in miles walked can be explained by the linear relationship between the in the number of shoes owned and the miles walked. 62% is attributable to other factors.

Researchers measured carapace (the exterior shell) length of 27 laboratory-raised lobsters of known age. The data on x = carapace length (in mm) and y = age (in years) in the following table were read from a graph that appeared in the paper. Age CarapaceLength Age CarapaceLength Age CarapaceLength 1.00 63.32 1.82 118.25 2.93 147.82 1.00 67.50 2.18 108.24 2.92 140.17 1.00 69.58 2.18 109.64 2.92 135.73 1.00 74.41 2.17 117.99 2.92 121.81 1.42 80.32 2.17 123.81 3.17 141.30 1.42 81.80 2.33 138.47 3.41 151.73 1.42 84.59 2.50 133.95 3.42 145.78 1.82 105.07 2.51 124.25 3.75 147.21 1.82 106.16 2.50 123.51 4.08 152.04 (a) Construct a scatterplot of these data, and then find the equation of the least squares regression line that describes the relationship between y = age and x = carapace length.

People familiar with these trees understand that the height of a California redwood tree is related to other characteristics of the tree, including the diameter of the tree at the breast height of a person. The data in the table represent the height (in feet) and diameter (in inches) at the breast height of a person for a sample of 21 California redwood trees. Assuming a linear relationship, use the least- squares method to compute the regression coefficients b0 and b1. State the regression equation that predicts the height of a tree based on the tree’s diameter at breast height of a person. Interpret the meaning of the slope in this equation. Predict the mean height for a tree that has a breast height diameter of 25 inches.

- An insurance company determines that a linear relationship exists between the cost of fire damage in major residential fıres and the distance from the house to the nearest fire station. A sample of 15 recent fires in a large suburb of a major city was selected. For each fire, the following variables were recorded: x= the distance between the fire and the nearest fire station (in miles) y= cost of damage (in dollars) The distances between the fire and the nearest fire station ranged between 0.7 miles and 6.1 miles. The correlation between cost and distance is 0.961. Test if the correlation is significant at a=.10. O No, the correlation is not significant because 0.961 does not exceed the critical value. O Yes, the correlation is significant because 0.961 exceeds the critical value. No, the correlation is not significant because 0.961 exceeds the critical value. O Yes, the correlation is significant because 0.961 does not exceed the critical value.
