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.
can you screenshot in and send it?
do u have a mac?
what type of computer do u have
there ya go
can you re post the question so i dont have to keep scrolling up

The profits earned in a year by some companies in a city are shown below: Company Profit A $160,000 B $140,000 C $130,000 D $1,120,000 E $150,000 Based on the data, should the mean or the median be used to make an inference about the profits earned by these companies? 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
im here, dont worry

The ages of two groups of dance students are shown in the following dot plots: src="http://learn.flvs.net/webdav/assessment_images/educator_mjmath2_v14/mjmath2_practice_m8_g10_c1.jpg" The mean absolute deviation (MAD) for group X is 3.07 and the MAD for group Y is 5.25. Which of the following observations can be made using these data? Group X has less variability in the data. Group X has greater variability in the data. Group Y has a lower range. Group Y has a lower mean.
it's not D
im pretty sure it's A
Jake wants to compare the mean height of the players on his favorite badminton and basketball teams. He creates the dot plots shown below: src="http://learn.flvs.net/webdav/assessment_images/educator_mjmath2_v14/mjmath2_practice_m8_g9_c2.jpg" The mean absolute deviation is 1.74 inches for the badminton team and 3.02 inches for the basketball team. Which of the following conclusions can be drawn from the data? The badminton players are all taller than the basketball players. The basketball players are all taller than the badminton players. There is more variability in the badminton team member heights. There is more variability in the basketball team member heights.
and ya, the other one was A

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
this is the second to last one?
B,Yes, this is a valid inference because she took a random sample of the neighborhood
