Daily Calorie Intake for Dieters
Class Frequency Class Boundaries Midpoint Relative Frequency Cumulative Frequency
1066–1125
1126–1185
1186–1245

1306–1365
1366–1425
Step 2 of 7 : Determine the frequency of the first class.

Answer 1

To determine the frequency of the first class, we need to count how many data points fall within the range of 1066-1125. Looking at the given data, we find that there is one data point within this range, which is 1075.

Therefore, the frequency of the first class, 1066-1125, is 1.
