To determine
The correct measurement that will agree with that obtained by the first student.

Option (a) 4.32cm±0.01cm , Option (b) 4.31cm±0.01cm and Option (c) 4.24cm±0.01cm .

Explanation

Given info: The thickness of book measured by one of the student is 4.3cm±0.1cm .

The thickness of book measured is 4.3cm±0.1cm .

The upper limit of thickness of book is,

4.3cm+0.1cm=4.4cm

The lower limit of thickness of book is,

4.3cm0.1cm=4.2cm

So, the range for the thickness of book lies between 4.2cm to 4.4cm .

Conclusion:

The measurement given in option (a) is 4.32cm±0.01cm . The range of thickness for the measurement lies between 4.31cm to 4.33cm and the actual range for the thickness of book lies between 4.2cm to 4.4cm . The range for the measurement in option (a) lies in between the actual range. Thus, option (a) is correct.

The measurement given in option (b) is 4.31cm±0.01cm . The range of thickness for the measurement lies between 4.30cm to 4.32cm and the actual range for the thickness of book lies between 4.2cm to 4.4cm . The range for the measurement in option (b) lies in between the actual range. Thus, option (b) is correct.

The measurement given in option (c) is 4.24cm±0.01cm . The range of thickness for the measurement lies between 4.23cm to 4.25cm and the actual range for the thickness of book lies between 4.2cm to 4.4cm . The range for the measurement in option (c) lies in between the actual range. Thus, option (c) is correct.

The measurement given in option (d) is 4.43cm±0.01cm . The range of thickness for the measurement lies between 4.42cm to 4.44cm and the actual range for the thickness of book lies between 4.2cm to 4.4cm . The range for the measurement in option (d) lies out of the actual range. Thus, option (d) is incorrect.
