Answer:
4 years old
Step-by-step explanation:
Harry = H
Brother = B
Aunty = A
Dad = B
H = ½ B
B = A - 28
A = D + 5
D = 31
A = 31 + 5 = 36
B = 36 -28 = 8 years old
H = ½ . 8 = 4 years old
Based on the scatter plot for this data, we can logically deduce that the association between them is a <u>positive association</u>.
<h3>What is a scatter plot?</h3>
A scatter plot can be defined as a type of graph which is used to graphically represent the values of two (2) variables, with the resulting points showing any association (correlation) between the data set.
<h3>Part A.</h3>
Based on the scatter plot for this data, we can deduce that the association between them is a <u>positive association</u> because the price and customer rating increases together.
<h3>Part B.</h3>
An example of a data point which would affect the appropriateness of using a linear regression model to fit all the data is car price of $4,601 and customer rating of 100.
<h3>Part C.</h3>
An example of a car that is cost effective and rated highly by customers is the one with a customer rating of 100 and sold at $3,500.
