Answer:
And the difference is given by:
Step-by-step explanation
We assume that th data is this one:
x: 242-255 -227-251-262-207-140
y: 91- 81 -91 - 92 - 102 - 94 - 91
Find the least-squares line appropriate for this data.
For this case we need to calculate the slope with the following formula:
Where:
So we can find the sums like this:
With these we can find the sums:
And the slope would be:
Now we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
The prediction for 253 seconds is:
And the difference is given by:
The double of 50 is 100 which means you would do 28*100=2800 now half of the answer is 2800/2=1400 which makes 1,400 your answer
