Explanation:

- The relationship between mode, median, and mean is given in the problem.

- The difference between the mode and median is stated as 38.

- To find what the difference between the median and mean could be, consider common scenarios such as skewed distributions.

- In a positively skewed distribution, mode < median < mean, so the difference median - mode = 38 could lead to a difference median - mean.

- The question requires calculation or knowing of statistical properties that are more complex without extra data.

- Option 1: 19 – This means median - mean is less than the first difference; typically plausible in a skewed data set.

- Option 2: 18 – This suggests a slightly smaller but similar scenario.

- Option 3: 24 – A larger difference between median and mean.

- Option 4: 22 – Still large but less than 24.

- Normal distributions or known properties like the Pearson’s First Skewness Coefficient can help.

The correct answer is option 1: 19.
