96% of the students have (1)∫ not less than 100 times.

The frequency of the first group is 1-0.96=0.04,

The sum of the first two groups of frequencies is 0. 12.

The frequency of the second group is 0. 12-0.04=0.08,

The number of people in the second group accounts for 0.08×100% = 8% of the total number of people in this transfer;

(2) The frequency of the second group is 0. 12-0.04=0.08,

∴ Therefore, the total number of people is 12 0.08 = 150 (people), that is, a total of 150 people are deployed this time;

(3) The number of people in the first group is 150×0.04=6 (people), and the number of people in the third and fourth groups is 5 1 and 45 respectively.

The excellent rate of this test is150-6-12-51-45150×100% = 24%;

So the answer is 24%.
