Answer:
A scatter plot is a plot or graph where you apply cartesian coordinates to display data.
You should have Plotted your graph already with "Birth weight" as the independent variable and Adult weight" as the dependent Variable.
Now
To answer the second part of the page.
It said
Which regression Equation would best model the data
Y=mx + c
You need to get this equation either using Micro soft excel(You can search for the steps online) or using the formula below
m= n(£xy) - (£x)(£y) / [ n(£x²) - (£x)²]
For C
C= £y - m(£x) / n
You'd need to draw a diagram and figure out these values
You need to be careful and know that £x² is not same as (£x)²
Know this to avoid mistakes.
Do this and fix your m and c values to get you regression line Equation.
Note: £ stands for Summation.
Evaluate those numbers like you would a statistical data.
Step-by-step explanation:
And For the Last... question...
We see a correlation... As the x value tends to increase.... y value also follows. This correlation is positive... So yeah... Its expected to grow exponentially
