Question

elijah is saving up for a new pair of sneakers. he tracks how much money he has in his savings account at the end of each week and plots the data on a scatterplot to see how his savings are growing over time.

question 3

are there any points that dont follow the trend closely? what could explain them?

Explanation:

Looking at the data, from week 1 to 3, the savings increase by 8 each week (10 to 18 to 26). Then from week 3 to 4, it increases by 3 (26 to 29), which is a deviation from the initial trend. From week 4 to 5, it jumps by 11 (29 to 40). Week 9 has a significant increase (75) compared to the previous week (56). Week 10 shows a decrease (63 from 75). These could be due to irregular income (e.g., a one - time bonus in week 9, unexpected expense in week 10), or miscalculations in recording.

Answer:

Yes, the points for week 4 (29), week 9 (75), and week 10 (63) deviate. Possible explanations: irregular income (e.g., bonus in week 9), unexpected expense (week 10), or recording errors.
