The value of a certain car when it was brand new with 0 mileage was $17,000 but the value dropped to $4,000 when the car acounulated 80,000 miles shown in the scatter plot below. Car's Mleage and Value S17.000 $2,000 Mileage Based on the data in the scatter plot, at what mileage was the car worth about $12,000? O 20,000 miles O 30,000 miles O 60,000 miles O 80,000 miles

Student grades on a chemistry exam were: 79, 77, 76, 82, 86, 50, 79, 81, 83, 99 Part (a) Construct a stem-and-leaf plot of the data. (Use the tens digit as the stem and the ones digit as the leaf. Enter your answers from smallest to largest, separated by spaces. Enter NONE for stems with no leaves.) 5   6   7   8   9   Are there any potential outliers? If so, which scores are they? Why do you consider them outliers? 1.There are no outliers in the data set because there are no large gaps in the stem-and-leaf plot. 2. The two outliers are 50 (because it lies 1.5 × IQR below the first quartile) and 99 (because it lies 1.5 × IQR above the upper quartile).     3.The only outlier is 99 because it is the largest value in the data set. 4.The only outlier is 50 because it lies 1.5 × IQR below the first quartile.

A County Board of Supervisors has appointed an urban planning committee to evaluate proposed community development projects. The committee is analyzing, among other things, data on household incomes in two cities within the county. They have collected data on the income of 80 households in each of the two cities. The histograms below show the distributions of the two sets of incomes (in thousands of dollars). Each histogram shows household income on the horizontal axis and number of households on the vertical axis. The means and standard deviations for the data sets are also given. City A City B 25- 25 - 20+ 20- 15- 15- 10+ 10- 5+ 5- 0- 10 20 30 40 50 60 70 80 90 100 10 20 30 40 50 60 70 80 90 100 City A mean: 38.13 thousand dollars City B mean: 55.13 thousand dollars City A standard deviation: 20.84 thousand dollars City B standard deviation: 14.71 thousand dollars The committee wants to use the Empirical Rule to make some approximations about both data sets. Unfortunately, it is…

Several years ago, the state of California launched an aggressively advertisement campaign against smoking. We've interviewed students from 16 college campuses in California and recorded for each campus the percentage of students who claimed that they had encountered assay least one anti smoking advertisement on campus in the past month.  Here are those percentages.  53 39 30 49 48 42 41 38 26 36 40 42 52 51 45 50 Construct a box and whisker plot for the data.
