Question

1) 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. in the study,30 students responded high interest, 40 students responded medium interest, and 30 students responded low interest. what is the relative frequency of students with high interest? 2) Monthly commissions class frequencies 600 up to 800 3 800 up to 1000 7 1000 up to 1200 11 1200 up to 1400 22 1400 up to 1600 40 1600 up to 1800 24 1800 up to 2000 9 2000 up to 2200 4 What is the relative frequency of those sales persona that earned 1600 or more 30.8?

Answer 1

1) 0.30

2) 0.308

Explanation:

1)

Interest Frequency

High 30

Medium 40

Low 30

Total frequency=30+40+30=100.

The relative frequency of student with high interest can be computed by dividing the frequency of high interest to the total frequency.

R.f of high interest=30/100=0.30

2)

Monthly Commission Frequencies

600-800 3

800-1000 7

1000-1200 11

1200-1400 22

1400-1600 40

1600-1800 24

1800-2000 9

2000-2200 4

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

The relative frequency of earning 1600 or more computed by dividing the frequency of earning 1600 or more to the total frequency.

R.f of earning more than 1600=24+9+4/120=37/120=0.308
