Question

for 7 days keep track of the number of pieces of mail you receive at your home. a. Put your data into a frequency table having intervals of 0–4, 5–9, 10–14, and 15–19. b. Use the frequency table to create a histogram of the data. c. Do you notice any patterns in the histogram?

Answer 1

Here is an example frequency table based on the data collected:

| Number of Pieces of Mail | Frequency |
|--------------------------|-----------|
| 0-4 | 3 |
| 5-9 | 2 |
| 10-14 | 1 |
| 15-19 | 1 |

To create a histogram, you would have a horizontal axis representing the intervals and a vertical axis representing the frequency of each interval.

Based on the data provided, the histogram would show bars for each interval, with the tallest bar representing the interval with the highest frequency.

Patterns that could be observed in the histogram might include a skew towards lower numbers of pieces of mail received, or perhaps a more even distribution across the intervals. The frequency table and histogram can help identify any trends or patterns in the amount of mail received over the 7-day period.
