This Question: 5 pts 3 of 8 (1 complete) Use the relative frequency table shown toMeasurement Class the right to calculate the number of the 300 measurements falling into each of the measurement classes. Then graph a frequency histogram for these data. 0.5-2.5 2.5-4.5 4.5-6.5 6.5-8.5 8.5-10.5 10.5-12.5 12.5-14.5 14.5-16.5 Relative Frequency 0.10 0.20 0.30 0.05 0.05 0.10 0.05 0.15 Fre-- Calculate the number of measurements that fall into each class. Class 0.5-25 2.5-4.5 4.5-6.5 6.5-8.5 8.5-10.5 10.5-12.5 12.5-14.5 14.5-16.5 Choose the correct graph below Click to select your answerls).

Explanation / Answer

1)

Frequancy F(x)= N*p(x)= N*Rel Frequency

N=300

2) Sum=400

A: 90-100 frequency= 400- (76+176+68+48)= 33

B: Relative frequency= 76/400= 0.19

C: Relative frequency= 176/400= 0.4375

D: Relative frequancy= 68/400= 0.17

E: Relative frequancy= 48/400= 0.12

Class Relative frequency Frequency 0.5-2.5 0.1 30 2.5-4.5 0.2 60 4.5-6.5 0.3 90 6.5-8.5 0.05 15 8.5-10.5 0.05 15 10.5-12.5 0.1 30 12.5-14.5 0.05 15 14.5-16.5 0.15 45 Sum 1 300
