Question

Josue and Sara both walk dogs during the week. They each walk 10 dogs in the morning and 10 other dogs in the afternoon. Select one of the groups to see how much the dogs in each group weigh. The heavier dogs usually have more energy and want to take longer walks than the smaller dogs.

Josue's dogs:
Morning:
26, 21, 15, 35, 38, 16, 13, 28, 30, 25
Afternoon:
15, 12, 9, 7, 44, 23, 55, 10, 37, 35
Sara's dogs:
Morning:
39, 21, 12, 27, 23, 19, 19, 31, 36, 25
Afternoon:
15, 51, 8, 16, 43, 34, 27, 11, 8, 39

1. Which dog-walker did you select? Circle one.

Josues

Comparing the Morning and Afternoon Groups
2. Create frequency tables to represent the morning and afternoon dogs as two sets of data. Group the weights into classes that range 10 pounds. (4 points: 2 points for appropriate intervals, 2 points for correctly portraying data)
10-20
20-30
30-40



















3. What is the median of the morning (AM) group? What is the median of the afternoon (PM) group? (2 points: 1 point for each answer)






4. What is the first quartile (Q1) of the morning (AM) group? What is the first quartile (Q1) of the afternoon (PM) group? (2 points: 1 point for each answer)






5. What is the third quartile (Q3) of the morning (AM) group? What is the third quartile (Q3) of the afternoon (PM) group? (2 points: 1 point for each answer)






6. Create a comparative box plot for the morning and afternoon dogs, and label each with its five-number summary. (6 points: 3 points for the correct form of plot, 3 points for appropriate labels)

7. What is the interquartile range (IQR) of the morning (AM) group? What is the interquartile range (IQR) of the afternoon (PM) group? (2 points: 1 point for each answer)






8. The average weights of the dogs are the same for the morning and afternoon groups. But based on your comparative box plot and the IQRs of the two groups, which group of dogs do you think would be easier to walk as one group? Why? (2 points: 1 point for answer, 1 point for justification)

Answer 1

ok so i dont have the total but this may help
mean-average of alll weights you can get it by adding all numbers up and the dividing by how numbers there are
median-like the name suggest the median is the vaule that is the middle. for example 2,3,6,5 ,8 then write it out as 2,3,5,6,8 and 5 is the mode. if it was something ike 1,2,3,4 you would add 2+3 then divide by 2
mode-the number that appears the most. for example the mode of 7,7,8,9,10 is 7
hope this helps :)

Answer 2

that may also help. idk how to explain it sorry
