Step-by-step explanation:

In finding the most precise measurement of the measurement of a minute long trial by the students , the average of the four experiments need to be calculated and the closest result to a minute (being the threshold ) is the most precise.

                                      Mila       Sonu        Parul

!st trial           57.3           58.8        59.5        62.1

Second trial  58               59          60           61

Third trial      50               60          60           70

Fourth trial   57.23          59.32     62.34      63.91

Total min.    222.53        237.12    241.84    257.01

Average min 55.63         59.28     60.46    64.25.

The most precise result is Mila experiment which is 59.28 being the closest measurement to a minute.
