Let's work through the questions one by one using the data provided in the image:

### a. How many of the albums have at least 15 songs?

We'll examine both Beyoncé and Taylor Swift's albums for this question.

#### Beyoncé:
According to the distribution chart for Beyoncé:
- There are 2 albums with 15 songs.
- There are 1 album with 16 songs.
- There are 2 albums with 17 songs.
- There is 1 album with 18 songs.

So, **6 albums** have at least 15 songs.

#### Taylor Swift:
For Taylor Swift:
- There is 1 album with 15 songs.
- There are 2 albums with 17 songs.
- There are 2 albums with 18 songs.
- There is 1 album with 19 songs.

So, **6 albums** have at least 15 songs.

### b. Compare the distributions.

Let's break down the comparison using the statistical information provided in the table.

1. **Mean**: 
   - Beyoncé's albums have an average of 14.429 songs.
   - Taylor Swift's albums have a slightly higher average of 14.7 songs.

2. **Standard Deviation (SD)**: 
   - Beyoncé's album distribution is more consistent, with a standard deviation of 1.813, compared to Taylor Swift’s higher SD of 2.263. This indicates that Taylor Swift’s album lengths are more spread out.

3. **Minimum and Maximum**:
   - Beyoncé's albums range from 12 to 16 songs, while Taylor Swift's range from 11 to 18 songs. Taylor Swift has a wider range of album lengths.
   
4. **Quartiles (Q1, Median, Q3)**:
   - For Beyoncé, the median number of songs per album is 15, while for Taylor Swift, it is 14.5. This shows that Beyoncé's album lengths tend to cluster slightly higher around the middle.
   - Beyoncé’s interquartile range (Q3 - Q1) is smaller (16 - 12 = 4) compared to Taylor Swift’s (17 - 13 = 4), which further indicates that Taylor Swift’s distribution is more spread out.

5. **Histogram**:
   - Beyoncé's distribution has a peak around 15-16 songs, with fewer albums at the extremes (12 or 17+ songs).
   - Taylor Swift's distribution shows a peak at 17-18 songs, but she also has albums at the lower end (11-13 songs), making her distribution more bimodal.

### Summary:
- Beyoncé’s album song counts are more consistent and clustered around 15-16 songs, with a narrow range.
- Taylor Swift’s albums show more variability, with a wider range of songs, and her distribution has two peaks around 13 and 17-18 songs.

Do you need more details or have any questions?

Here are 5 related questions:
1. How can we calculate the variance from the standard deviation?
2. Why does a higher standard deviation indicate more variability in album lengths?
3. What conclusions can we draw about the interquartile range between the two artists?
4. How would adding another album with more songs (e.g., 20+) affect Taylor Swift's distribution?
5. Can we use this data to predict the number of songs on future albums?

**Tip:** When comparing distributions, focus on both measures of center (mean, median) and spread (range, standard deviation) for a thorough analysis.
