Question

The dot plots below show the runs scored in each of the first games of the season by the Hawks and the Eagles. Runs Scored (Ha Runs Scored Part A What is the mean number of runs for the Hawks? Answer _ Part B Add two points to the dot plot for the Hawks that show possible runs scored in the next two games if the mean number of runs decreases and the range increases. Part CAdd two points to the dot plot for the Eagles that show possible runs scored in the next two games if the mean number of runs stays the same.

Answer 1

Part B: 8 and 2 (more answers ofc)

Part C: Two more dots on 6 (more than one answer tho)

Explanation:

Part B:

The added number of dots is 39 at the beginning and the mean is 3.9. (39/10). Since we have to add 2 dots the equation will be (39 + ? + ?) / 12 = Less than 3.9. We also need the range to increase. This means that one of the blanks must be larger than 7 (the largest dot on the dot plot!) I just went with 8 to keep the mean as small as possible. This leaves 1 more blank to figure out. There are multiple answers to this problem but I went with 2 just because then the mean would be 3.5 a better answer than something like 3.58333333333.

Part C:

If you think about it all the dots added up should be 6x12 = 72. Currently all the dots add up to 60. 72-60 is 12. This means that 12 is equal to 2 dots. I guess you could also do 5 and 7, 8 and 4, etc.

G'day
