Question

A group of 100 students was surveyed about their interest in a new international studies program. interest was measured in terms of high, medium, or low. 30 students responded high interest; 40 students responded medium interest; 30 students responded low interest. what is the relative frequency of students with high interest? show your answers to two decimal places. for example, 0.25.

Answer 1

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
