The correct answer is option A. 1,18.
Linear regression is a method used to identify the trend Or similarity between two sets of data. All the given points of the data set are plotted and a straight line is drawn with the points. The line is called a line of regression.
F Test is a test that is used to check if the given line of regression is a good fit for the given data set or not. F ratio is the ratio obtained by dividing the two mean square values of the data set.
The numerator of the given regression is always 1
The denominator of the regression is given by n-2=20-2=18.

Explanation of Advantages:
Co-education has many advantages in education. It is important in many aspects, including the following:
There is more diversity in a classroom setting of co-education, providing more experiences and perspectives for the class to judge and learn from.
There are fewer buildings needed when operating under co-education because classes are not split into multiple schools, lowering the cost of maintenance of a school (electrical maintenance, custodial maintenance).
Fewer teachers and staff at a school are needed with co-education. Larger groups of students are able to learn together, in the same classroom, meaning that an educator can teach more students under co-education standards than an educator in a separate education context. This lowers the cost of pay for teachers, and each individual teacher can have a larger salary. With fewer educators, fewer interviews for positions of teachers are needed, saving a school board more time (which they can use to evaluate other important aspects).
Additionally, students of different sexes will have the same background information needed to learn at a higher level. Standards set across one co-ed school are going to be more consistent within their classes, as opposed to two different classes, comprised of separated students, and different teachers. This makes it easier to continue education, as more opportunities are open to all people.
Ultimately, there is a stronger connection and mutual respect between students of diverse backgrounds, and empathy between diverse groups is established, allowing brighter futures for humanity.
Answer:
Located off the coast of Abu Dhabi emirate, the small island of Umm an-Nar features an archaeological site that has yielded significant finds that have helped to illuminate the culture and lifestyle of Bronze Age inhabitants of the United Arab Emirates.
Between approximately 2500 BCE and 2000 BCE, this small island was home to a relatively large settlement that played an active role in regional commerce, with artefacts showing that people on the island traded with civilisations as far away as ancient Mesopotamia (modern-day Iraq) and the Indus Valley Civilisation
