Answer:
Step-by-step explanation:
-3.5 means -(3 + )
In other words, -3.5 =
When we draw two numbers and
on a number line,
comes first from left to right.
We know that all the numbers on a number line from left to right are in increasing order.
Therefore, is smaller than
.
Lauren is not correct.
The value for r = - 0.8535 , there is strong correlation between the variables.
<h3>What is a correlation coefficient ?</h3>Correlation coefficient describes the relationship between the two variables in the data .
The data given is
(1, 7), (2, 5), (3, -1), (4, 3), (5, -5)
Assuming Linear Regression ,
The data is plotted on the graphing calculator
The value for r = - 0.8535
as the value is in the range of - .85 to -1 , therefore there is strong correlation between the variables.
