Hypothesis testing and estimation are types of descriptive statistics. (a) True

(b) False

(c) None of these

(d) All of the above

✅ Correct option: (b) False

Explanation:

Hypothesis testing and estimation fall under inferential statistics, not descriptive statistics. Descriptive statistics focus on summarizing and organizing data using measures such as mean, median, mode, range, and standard deviation. Inferential statistics allow researchers to make conclusions about populations based on sample data. Hypothesis testing evaluates assumptions, while estimation predicts population parameters. Therefore, the statement is false.
