Answer:
I. Poor scale, wasted space
III. No units for dependent variable
Explanation:
Given
See attachment for graph
Required
Identify the mistakes
The mistakes are
(I) Poor scale
The unused space on the vertical axis is much. A better scale would have reduced the amount of unused space.
(II) There is a unit (1 minute) in the independent variable; so, this is not a mistake
(III) No unit on the dependent variable
Yes, this is part of the mistake, as there is no units on the x-axis
(IV) Decimals
This is not a compulsory requirement of plotting graphs; so, this is also not a mistake
Hence,
Hence (I) and (III) are mistakes on the graph
