Step1: Recall measure definitions

Mean is the average, median is the middle - value, mode is the most frequent value.

Step2: Analyze (a)

Maya wants the most - frequent letter, so mode is appropriate.

Step3: Analyze (b)

Salaries have no repeated values, and there may be outliers. Median is a better measure than mean to summarize as it is not affected by outliers.

Call lengths are a set of ordered values with no extreme outliers. Mean can be used to summarize the data.

(a) Mode
(b) Median
(c) Mean
