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,for an alpha = .05 level,the critical value from the chi-square table is 9.4877.

To test independence between two categorical variables using chi-square test, we need to calculate the chi-square statistic and compare it with the critical value from the chi-square table at a given level of significance (alpha). In this case, the observed chi-square value is 19.484, which exceeds the critical value of 9.4877. Therefore, we reject the null hypothesis of independence and conclude that there is a significant relationship between age and preferred news source. Thus, the answer is A, True.
