Step-by-step explanation:
The histogram shows the sizes (in acres) of 44 vineyards.
a. Approximately what percentage of these vineyards are at or over 210 acres?
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
b. Describe the distribution (shape, center, spread, unusual features).
- A. The distribution is uniform.
- B. The distribution is bimodal.
- C. The distribution is unimodal.
Is the distribution symmetric or skewed?
- A. The distribution is skewed to the left.
- B. The distribution is symmetric.
- C. The distribution is skewed to the right.
Which of the following best describes the center?
- 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.
- C. The center is best described by the median since the distribution is skewed to the left and has an outlier.
What is the spread?
- The acreage ranges from 30 to 270 acres.
- 30, 90, 120, 210, 240, 270
Describe any unusual features.
- A. There are no unusual features.
- B. Most of the vineyards have close to the same number of acres.
