Question

Suppose the scatter plot shows the results of a survey of 21 randomly selected males ages 24 to 35. Using age as the explanatory variable, choose the appropriate description for the graph. Explain your reasoning. (a) Age and body temperature (b) Age and balance on student loans (c) Age and income (d) Age and height The response variable is because you would expect this variable and age to have Y and variation for adult males. balance on student loans height body temperature income 24 26 28 30 32 34 36

Explanation / Answer

the response variable is balance on student loans

it can not be height because for some data points we have the data points lying on the x axis which means height=0 which is absurd

for the same reason it can not be body temperature

it can not be income also, because according to the graph for people ages 24-27 the income is higher where as for people with ages 30-34 it is zero which is again absurd

this variable balance on student loans and age to have negative correlation which is visuable from the graph

because naturally as people get older they will start to return the loan amounts hence balance on student loans would become low.

and high variation for adult males.
