Answer:
- See below and attachment
- Correct answer options are in bold and underlined
Step-by-step explanation:
The histogram shows the sizes (in acres) of 44 vineyards.
<u>a. Approximately what percentage of these vineyards are at or over 210 acres? </u>
10+13 = 23 of the vineyards are at or over 210 acres. Total is 44, so
- 23/44*100% = 52% rounded to the nearest percent
<u>b. Describe the distribution (shape, center, spread, unusual features). </u>
- A. The distribution is uniform.
- <u>B. The distribution is bimodal. </u>
- C. The distribution is unimodal.
<u>Is the distribution symmetric or skewed? </u>
- <u>A. The distribution is skewed to the left. </u>
- B. The distribution is symmetric.
- C. The distribution is skewed to the right.
<u>Which of the following best describes the center? </u>
- A. The center is best described by the mean since the distribution is symmetric and there are no outliers.
- B. The center is best described by the median since the distribution is skewed to the right and has an outlier.
- <u>C. The center is best described by the median since the distribution is skewed to the left and has an outlier. </u>
<u>What is the spread?</u>
- The acreage ranges from 30 to 270 acres.
- 30, 90, 120, 210, 240, 270
<u>Describe any unusual features. </u>
- A. There are no unusual features.
- B. Most of the vineyards have close to the same number of acres.
- <u>C. There is one vineyard that has considerably fewer acres, 0 to 30 acres, than the rest.</u>

Mr. Mole's burrow was at an altitude of 6 meters below the ground.
Step-by-step explanation:
Step 1:
We need to determine the distance that Mr. Mole covers in a single minute.
To do that we divide the difference in values of altitude by the difference in the time periods.
For the first case, Mr. Mole had traveled -18 meters in 5 minutes.
We also have, he traveled -25.2 meters in 8 minutes.
Step 2:
The distance he covered in 1 minute
So with every minute, Mr. Mole digs down an additional 2.4 meters below the surface.
To determine where Mr. Mole's burrow is we subtract the distance traveled in 5 minutes from -18.
The altitude of Mr. Mole's burrow
So Mr. Mole's burrow was at an altitude of 6 meters below the ground i.e. -6 meters.
