Answer:
Range = 24
Step-by-step explanation:
Record of percentage
59, 61, 83, 67, 81, 80, 81
We need to find the range
To find the range , we order the numbers from smallest to largest.
Then Subtract the smallest number from largest number.
When we arrange the numbers it becomes
59, 61, 67, 80, 81, 81, 83
Smallest number is 59 and largest number is 83
Range = 83 - 59 =24
Answer:
B) -0.98
Step-by-step explanation:
Correlation coefficient is usually denoted with numbers ranging from 1 to -1. Automatically, this eliminates option C) as our possible answer, since -1.43 is outside the range.
The trend shown in the scatter plot describes a negative relationship because, as the values in the Y-axis decreases, the values at the X-axis increases. The possible correlation coefficient we are likely to get is one that is negative. This eliminates option A and option and option D is our possible correlation coefficient for the scatter plot given since both values are positive.
Option B) -0.98, best represents the correlation coefficient of the given scatter plot. Since the points on the scatter plot seem closely aligned on a straight line, a negative value if -0.98 is mostly the possible one to get.
