The curve represents the estimates and the points represent the actual values. The estimate is least accurate at point x = 11 hrs. The curve is much lower than the point (actual value) at x = 11 hrs.

NOt able to understand the second questiono? What does least accurate mean? If there is a deviation in the graph, can that mean that it is least accurate?KarishmaB Can you help?

Hi Mam,

Can you please tell me why answer 10 to 12 is not correct for Q1

The value at 10 hrs is about 5% and at 11 hrs is about 10%. That is a 5% increase.
The value at 12 hours is about 9% so from 10 hrs to 12 hrs, the increase is only 4%.
Hence maximum increase happened from 10 hrs to 11 hrs.

Hi Ma'am,

We have to consider 10% ( the black outside the line) for 10 hrs.. I thought that we had to consider the value that appears on the line.


Thanks for your explanation

The line is a trend line. Otherwise, the points data don't make sense.
