Consider the following data representing the price of refrigerators (in dollars): 1218, 1253, 1121, 1282, 1261, 1263, 1349, 1390, 1316, 1227, 1140, 1245, 1158, 1168, 1195, 1225, 1161, 1405, 1320, 1405, 1122. Step 2 of 7: Determine the frequency of the fifth class.

Consider the following data representing the price of refrigerators (in dollars): 1218, 1253, 1121, 1282, 1261, 1263, 1349, 1390, 1316, 1227, 1140, 1245, 1158, 1168, 1195, 1225, 1161, 1405, 1320, 1405, 1122. Step 2 of 7: Determine the frequency of the fifth class.

Answer

To determine the frequency of the fifth class, first identify the boundaries for that specific class from the table. The table shows the fifth class as 1308-1357. Next, examine the provided list of refrigerator prices and count how many values fall within this range (greater than or equal to 1308 and less than or equal to 1357). Let's check each data point: 1218 (No), 1253 (No), 1121 (No), 1282 (No), 1261 (No), 1263 (No), 1349 (Yes), 1390 (No), 1316 (Yes), 1227 (No), 1140 (No), 1245 (No), 1158 (No), 1168 (No), 1195 (No), 1225 (No), 1161 (No), 1405 (No), 1320 (Yes), 1405 (No), 1122 (No). The values that fit the criteria are 1349, 1316, and 1320. Counting these values gives a total of 3. Therefore, the frequency of the fifth class is 3.
