A study was recently conducted in which people were asked to indicate which news medium was their preferred choice for national news.The following data were observed:  Given this data,if we wish to test whether the preferred news source is independent of age,the cell with the largest expected cell frequency is also the cell with the largest observed frequency.

The statement is false. The cell with the largest expected frequency may not always be the same as the cell with the largest observed frequency. Even if the expected and observed frequencies are close, it does not necessarily mean that the preferred news source is independent of age. A statistical test, such as a chi-square test, should be conducted to determine the independence of the variables.
