Question

The scatter plot shows the median household income x in thousands of dollars, and the number of adults per 1,000 people with bachelors degree y of 50 U.S states. The line y=4.08x+63.13 is a good fit for this data

Answer 1

So,

The line:

`y=4.08x+63.13`

Is a good fit of the data given.

To predict the number of bachelor's degrees in Mississippi, we replace x by 40.6 and operate:

`\begin{gathered} y=4.08(40.6)+63.13 \\ y=228.778 \end{gathered}`

The number of bachelor's degrees per 1000 people when x=40.6 median income, is predicted as 228.778.
