Answer 1

12 observations in a data are written in descending order. If the first observation is doubled, the median will remain same.

Explanation:

When observations are written in descending order, the first observation is the largest value. Since the median for 12 observations depends entirely on the 6th and 7th terms, altering the first term leaves the median unaffected.
