Question

Find the mean and median of the past week's temperatures
Sunday=102 degrees Fahrenheit
monday= 105
tuesday=107
wednesday=109
thursday=110
friday=109
saturday=109

Answer 1

To find the mean and median of the past week's temperatures, we first list the temperatures for each day:

- Sunday: 102 degrees
- Monday: 105 degrees
- Tuesday: 107 degrees
- Wednesday: 109 degrees
- Thursday: 110 degrees
- Friday: 109 degrees
- Saturday: 109 degrees

**Mean Calculation:**

1. Add all the temperatures together:
\[
102 + 105 + 107 + 109 + 110 + 109 + 109 = 751
\]

2. Count the number of days (which is 7).
3. Divide the total by the number of days to find the mean:
\[
\text{Mean} = \frac{751}{7} \approx 107.29 \text{ degrees}
\]

**Median Calculation:**

1. First, we arrange the temperatures in ascending order:
\[
102, 105, 107, 109, 109, 109, 110
\]

2. Since there are 7 numbers (an odd count), the median will be the middle number, which is the 4th number in the ordered list:
\[
\text{Median} = 109 \text{ degrees}
\]

**Summary:**
- Mean temperature: approximately 107.29 degrees Fahrenheit
- Median temperature: 109 degrees Fahrenheit
