Answer:
The best estimate of the correlation coefficient is 0.9 from the given data.
Step-by-step explanation:
From the scatter plot, the line of best fit will have a positive slope.
So, the correlation coefficient ,
is greater than 0.
so,
≠ - 0.9
Also, there is a deviation from absolute linearity.
So,
≠ 1
Again from the scatter plot it is closer to linearity than further.
Hence,
≠ 0.3 .
So
= 0.9
A = 1/2(15+7+15+7)(13)
A= 1/2(44)(13)
A = 286
answer
286
first, find the square root of 45. and make x normal. a square root cancels out a square. It should be 6.7x
