The value of correlation coefficient (r) for the dataset is 0.981
<h3>What is correlation coefficient (r)?</h3>
The correlation coefficient (r) is used to determine the closeness and association of a scatter plot points.
The dataset is given as:
- x: 8 15 3 7 2 14
- y: 15 21 6 12 3 20
Using a graphing calculator, we have the following parameters:
<h3>X Values
</h3>
- ∑x = 49
- Mean = 8.167
- ∑(X - Mx)2 = SSx = 146.833
<h3>Y Values
</h3>
- ∑y = 77
- Mean = 12.833
- ∑(Y - My)2 = SSy = 266.833
<h3>X and Y Combined
</h3>
- N = 6
- ∑(X - Mx)(Y - My) = 194.167
The correlation coefficient (r) is then calculated as:
This gives


Approximate

Hence, the value of correlation coefficient (r) for the dataset is 0.981

Answer:
The square root of 120 is about 10.95
Step-by-step explanation:
Answer:
The top right answer choice is correct.
2.3 x 12 = 27.6
27.6 > 27.1
Step-by-step explanation:
Well first off, we know that:
1 foot = 12 inches
To compare the two, we first want to covert 2.3 feet into inches.
2.3 x 12 = 27.6 inches
Now that we have our two values, we need to decide which is greater than the other.
27.6 or 27.1
Both values have a decimal that shows tenths. In this problem, 6 tenths is larger than 1 tenth. Therefore:
27.6 inches > 27.1 inches
