Solution Steps

Step 1: Organize the Data

The given data for the number of elementary school children in 16 school districts is: \[ \{1952, 2400, 1139, 2500, 1260, 3712, 3110, 4800, 3254, 1050, 3252, 1503, 1734, 3640, 3414, 4400\} \]

Step 2: Create Frequency Distribution

We need to create a cumulative frequency distribution for the given intervals: \[ 1000-1999, 2000-2999, 3000-3999, 4000-4999 \]

Step 3: Calculate Cumulative Frequencies
  • For \(1000-1999\): 1139, 1260, 1050, 1503, 1734 (5 values)
  • For \(2000-2999\): 1952, 2400, 2500 (3 values)
  • For \(3000-3999\): 3110, 3254, 3252, 3712, 3640, 3414 (6 values)
  • For \(4000-4999\): 4800, 4400 (2 values)

Cumulative frequencies:

  • \(1000-1999\): 5
  • \(2000-2999\): 5 + 3 = 8
  • \(3000-3999\): 8 + 6 = 14
  • \(4000-4999\): 14 + 2 = 16

Final Answer

\[ \begin{array}{|c|c|} \hline \text{Students in a District} & \text{Cumulative Frequency} \\ \hline 1000-1999 & 5 \\ \hline 2000-2999 & 8 \\ \hline 3000-3999 & 14 \\ \hline 4000-4999 & 16 \\ \hline \end{array} \]

{"axisType": 3, "coordSystem": {"xmin": 1000, "xmax": 5000, "ymin": 0, "ymax": 16}, "commands": ["y = 5 if x <= 1999 else 8 if x <= 2999 else 14 if x <= 3999 else 16"], "latex_expressions": ["$Cumulative Frequency$"]}
