Finding the correlation coefficient, it is found that the regression line shows a:
negative trend line with a strong relationship.
<h3>What is a correlation coefficient?</h3>
- It is an index that measures correlation between two variables, assuming values between -1 and 1.
- If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
- If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.
Inserting the values of a table, the x-values as 25, 28, 30, 31, 33, 40, and the y-values as 7.5, 6, 5.5, 5, 4.5, 4.5, the coefficient is of -0.85, which is negative and strong.

Answer:
22.6 inches
Step-by-step explanation:
The circumference of a circle is given by
C = pi *d
The diameter is 7.2 inches
Approximating pi by 3.14
C = 3.14 * 7.2
C = 22.608
Rounding to the nearest tenth
C = 22.6
