Question
Is it reasonable to treat the following as a sample from an approximately normal population? Explain.
Transcribed Image Text:**Part 3 of 4**
**(c) The following histogram illustrates a sample.**
- The histogram displays the relative frequency of different intervals of a dataset.
- The intervals are on the x-axis, ranging from 0 to 16, in increments of 2.
- The relative frequency is plotted on the y-axis, which measures values from 0.00 to 0.25.
**Histogram Details:**
- **0–2:** Relative frequency = 0.05
- **2–4:** Relative frequency = 0.05
- **4–6:** Relative frequency = 0.05
- **6–8:** Relative frequency = 0.05
- **8–10:** Relative frequency = 0.10
- **10–12:** Relative frequency = 0.20
- **12–14:** Relative frequency = 0.20
- **14–16:** Relative frequency = 0.10
Below the histogram, there is a dropdown menu with the options to choose the feature the plot reveals:
- Outlier(s)
- A large degree of skewness
- More than one distinct mode
- None of these features
**(d) The following stem-and-leaf plot illustrates a sample.**
- Stem-and-leaf plot details:
- **0:** | (blank)
- **1:** | 46
- **2:** | 01378
- **3:** | 169
- **4:** | 35
- **5:** | 3
- **6:** | 1
- **7:** | 34
- **8:** | 4799
- **9:** | 356689
- **10:** | 123
- **11:** | 8
Below the stem-and-leaf plot, there is a dropdown menu with the options to choose the feature the plot reveals:
- Outlier(s)
- A large degree of skewness
- More than one distinct mode
- None of these features
There is a second dropdown menu to choose whether we treat the sample as being from an approximately normal distribution.

(a) The following dotplot illustrates a sample.
- **Dotplot Description:**
- The dotplot shows individual data points along a horizontal axis ranging from 0 to 10.
- The points are mostly clustered around the center of the range.
- **Analysis Dropdown Choices:**
- an outlier
- a large degree of skewness
- more than one distinct mode
- none of these features
- **Conclusion Dropdown Choices:**
- can
- cannot
The dotplot reveals (choose one) [an outlier]. Therefore, we (choose one) [cannot] treat this as a sample from an approximately normal distribution.
(b) The following boxplot illustrates a sample.
- **Boxplot Description:**
- The boxplot displays a box with whiskers extending from the lower end at 0 to approximately 6.
- The box itself begins around 2 and ends around 5.5, with a median line inside it at about 4.
- **Analysis Dropdown Choices:**
- outlier(s)
- a large degree of skewness
- more than one distinct mode
- none of these features
- **Conclusion Dropdown Choices:**
- can
- cannot
The boxplot reveals (choose one) [none of these features].
