Answer 1

The reference category for the dummy variable categorizing gender, when setting 1 for male and 0 for female, would be female. This category serves as the baseline for comparison in the statistical model.

Step-by-step explanation:

In the context of a dummy variable used in statistical analyses to categorize gender, if you define 1 for male and 0 for female, the reference category would be female. The reference category is the group against which comparisons are made; it represents the baseline in the model. In statistical terms, when using binary dummy variables, the category coded as 0 is generally the reference category.In the realm of trigonometry, the work of the Indian philosopher Aryabhata provided a strong foundation for the field. The cultural exchange between Greek, Indian, and Arab mathematicians significantly propelled the understanding and development of mathematics across civilizations. This exchange played a pivotal role in the growth of scientific knowledge during the Scientific Revolution and the Enlightenment, with the development of algebra being a direct result of this scholarly interconnectivity.
