Question

Consider the following data representing the price of refrigerators (in dollars). 1178, 1407, 1350, 1255, 1345, 1345, 1192, 1345, 1408, 1426, 1402, 1218, 1250, 1203, 1251, 1213, 1216, 1225, 1206, 1370, 1357 Price of Refrigerators (in Dollars) Class Frequency Class Boundaries Midpoint Relative Frequency Cumulative Frequency 1160–1209 1210–1259 1260–1309 1310–1359 1360–1409 1410–1459 Step 6 of 7 :

Calculate the relative frequency of the sixth class. Determine your answer as a simplified fraction.

Answer 1

Sixth class is 1410 - 1459

total frequency = total number of data values = 21

Frequency for class sixth is 1 because only 1426 is there in class 1410-1459

Relative frequency = (class frequency)/(total frequency)

So, relative frequency = 1/21
