Math Problem Statement

Complete the grouped frequency distribution for the given temperature data: 114, 118, 108, 110, 109, 115, 112, 116, 107, 103, 104, 113, 117, 95, 100, 99, 104, with class intervals 94.5-100.5, 100.5-106.5, 106.5-112.5, 112.5-118.5.

Solution

To determine the frequency distribution for the given temperature data, follow these steps:

  1. Class width is already given as 6.
  2. Count the number of data points that fall into each temperature range (class).

Step 1: Organize the data

The temperatures given are:

  • 114, 118, 108, 110, 109, 115, 112, 116, 107, 103, 104, 113, 117, 95, 100, 99, 104

Step 2: Classify the data into intervals

The class intervals are:

  • 94.5 to 100.5
  • 100.5 to 106.5
  • 106.5 to 112.5
  • 112.5 to 118.5

Step 3: Tally and count frequencies

  • 94.5 to 100.5:

    • 95, 99, 100 → 3 values
  • 100.5 to 106.5:

    • 103, 104, 104 → 3 values
  • 106.5 to 112.5:

    • 107, 108, 109, 110 → 4 values
  • 112.5 to 118.5:

    • 112, 113, 114, 115, 116, 117, 118 → 7 values

Step 4: Final Table

Temperatures (in °F)Frequency
94.5 to 100.53
100.5 to 106.53
106.5 to 112.54
112.5 to 118.57

Final Answer

The frequencies for the grouped distribution are:

  • 94.5 to 100.5 → 3
  • 100.5 to 106.5 → 3
  • 106.5 to 112.5 → 4
  • 112.5 to 118.5 → 7
