The dot plots below show the distances traveled by two groups of bikers: : Two dot plots are labeled Group A and Group B. The horizontal axis is labeled Distance Traveled and marked from 15 to 40 at increments of 5 for both dot plots. Group A shows 9 dots on 15, 8 dots on 20, 3 dots on 25, 6 dots on 30, 4 dots on 35. Group B shows 10 dots on 20, 6 dots on 25, 4 dots on 30, 9 dots on 35 and 6 dots on 40. Which of the following inferences can be made using the dot plots? There is no overlap between the data. The range of the two groups is different. Group A has a higher mean than group B. Group B has a higher mean than group A.

Mean, because it is in the center of the data Median, because it is in the center of the data Mean, because there are no outliers that affect the mean Median, because there is an outlier that affects the mean

Sue wants to know how many families in her small neighborhood of 50 homes would volunteer to help at a neighborhood animal shelter. She put all the addresses in a bag and drew a random sample of 25 addresses. She then asked those families if they would volunteer to help at the shelter. She found that 18% of the families would volunteer to help at the shelter. She claims that 18% of the neighborhood families would be expected to help at the animal shelter. Is this a valid inference? Yes, this is a valid inference because the 25 families speak for the whole neighborhood Yes, this is a valid inference because she took a random sample of the neighborhood No, this is not a valid inference because she only asked 25 families No, this is not a valid inference because she did not take a random sample of the neighborhood
