Task 1
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
b. Use the frequency table to create a histogram of the data.
c. Do you notice any patterns in the histogram?
Task 2
a. Pick 9 different dog breeds and find their average weights. List each breed
Task 3
Pick a city in Maryland and determine the average high temperatures for each month. Record this in a table.
2. What is themand-ntemperlot for the data.
c. 75% of the temperatures are below what value? How do you know?
d. 75% of the temperatures are above what value? How do you know?
e. What conclusions can you draw about the temperature in Maryland?
Task 1
Frequency Table:
0-4: 3
5-9: 2
10-14: 1
15-19: 1
Histogram:
x-axis
0-4 | ***
5-9 | **
10-14| *
15-19| *
Patterns in the histogram:
From the histogram, we can see that most days had 0-4 pieces of mail received, with a gradual decrease in frequency as the number of pieces of mail increased.
Task 2
Average weights of 9 different dog breeds:
1. Labrador Retriever - 70 pounds
2. German Shepherd - 80 pounds
3. Golden Retriever - 60 pounds
4. Bulldog - 50 pounds
5. Poodle - 45 pounds
6. Boxer - 65 pounds
7. Beagle - 25 pounds
8. Rottweiler - 100 pounds
9. Siberian Husky - 45 pounds
Task 3
Average High Temperatures in a city in Maryland:
| Month | Avg High Temp (F) |
|----------|-------------------|
| January | 40 |
| February | 45 |
| March | 50 |
| April | 60 |
| May | 70 |
| June | 80 |
| July | 85 |
| August | 85 |
| September| 75 |
| October | 65 |
| November | 55 |
| December | 45 |
a. The median temperature for the data is 65 degrees Fahrenheit.
b. 75% of the temperatures are below 80 degrees Fahrenheit. This is known because 80 degrees Fahrenheit falls within the 75th percentile of the data.
c. 75% of the temperatures are above 45 degrees Fahrenheit. This is known because 45 degrees Fahrenheit falls below the 25th percentile of the data.
e. Based on the data, it can be concluded that the temperature in Maryland generally increases from January to July, with the highest average high temperatures occurring in July and August. The temperature then starts to decrease from September onwards.
