Min: 10 Q1: 26 Median: 34 Q3: 44 Max: 47

3. The boundaries for outliers are 26 – 1. 5(44 – 26) = -1 and 44 + 1
The boundaries for outliers are 26 – 1.5(44 – 26) = -1 and (44 – 26) = 71, so there are no outliers.

4. Here are the numerical summaries and boxplots for each distribution:n

5. Shape: The female distribution is approximately symmetric but the male distribution is slightly skewed to the right.
Center: The median number of contacts for the females is slightly higher than the median number of contacts for the males.
Spread: The distribution of contacts for males is more spread out than the distribution of females since both the IQR and range is larger.
Outliers: Neither of the distributions have any outliers.
Conclude: In the samples, females have more contacts than males, since both the mean and median values are slightly larger. However, the differences are small so this is not convincing evidence that one gender has more contacts than the other.
