Consider the following data representing the price of laptop computers (in dollars). 1429, 1284, 1288, 1294, 1468, 1425, 1256, 1374, 1356, 1461, 1428, 1197, 1331, 1143, 1127, 1279, 1475, 1423, 1117, 1423, 1151. Step 2 of 7: Determine the frequency of the fourth class.

Consider the following data representing the price of laptop computers (in dollars). 1429, 1284, 1288, 1294, 1468, 1425, 1256, 1374, 1356, 1461, 1428, 1197, 1331, 1143, 1127, 1279, 1475, 1423, 1117, 1423, 1151. Step 2 of 7: Determine the frequency of the fourth class.

Answer

To find the frequency of the fourth class, we first identify the range for that class from the provided frequency distribution table. The fourth class is defined by the interval 1296-1355. Next, we examine the provided data set of laptop prices and count how many values fall within this specific range. The data set is: 1429, 1284, 1288, 1294, 1468, 1425, 1256, 1374, 1356, 1461, 1428, 1197, 1331, 1143, 1127, 1279, 1475, 1423, 1117, 1423, 1151. Looking through these numbers: 1429 (No), 1284 (No), 1288 (No), 1294 (No), 1468 (No), 1425 (No), 1256 (No), 1374 (No), 1356 (No), 1461 (No), 1428 (No), 1197 (No), 1331 (Yes, falls between 1296 and 1355), 1143 (No), 1127 (No), 1279 (No), 1475 (No), 1423 (No), 1117 (No), 1423 (No), 1151 (No). Only one value, 1331, falls within the interval 1296-1355. Therefore, the frequency of the fourth class is 1.
