The answer is .30

Since 30 students responded high interest so the relative frequency of students with high interest is  

30/100=0.30

So required relative frequency is 30%.

Total frequencies: 3+7+11+22+40+24+9+4=120

The total frequencies of those who sales 1600 or more is 24+9+4=37

So required relative frequency will be

37/120 = 0.308
