Step 1/7 Certainly! Let's break down the process of determining the upper class boundary for the fourth class. Step 2/7 Step 1: Identify the class intervals. The class intervals are given as ranges of calorie intake values. The fourth class interval is from 1320 to 1379. Step 3/7 Step 2: Understand the concept of class boundaries. Class boundaries are the actual limits of the classes. They are used to ensure that there are no gaps between the classes. The upper class boundary of a class is the highest value that can belong to that class. Step 4/7 Step 3: Determine the lower class boundary of the next class. To find the upper class boundary of the fourth class, we need to look at the lower class boundary of the fifth class. The fifth class interval is from 1380 to 1439. Therefore, the lower class boundary of the fifth class is 1380. Step 5/7 Step 4: Calculate the upper class boundary for the fourth class. The upper class boundary for the fourth class is one unit less than the lower class boundary of the fifth class. This is because we assume that the data is continuous, and there are no gaps
