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.

A syndrome is a set of interrelated medical signs and symptoms that are often associated with a specific disease or disorder. [1] The word comes from the Greek σύνδρομον, meaning "meeting". In some cases, the terms syndrome, disease, and disorder are used interchangeably because the syndrome is so closely related to etiology or cause.
This terminology substitution often confuses the reality and meaning of medical diagnosis [3]. This is especially true for hereditary syndromes. About one-third of all phenotypes listed in OMIM are described as dysmorphic, mainly referring to facial shape. For example, Down syndrome.

The answer to this question is explained below.
Explanation:
There are two parts in this question. One is the possible heuristics when deciding whether you should study hard for the test, and secondly when ask someone for a date, or accept a date.
Studying hard for the test:
In deciding whether study hard for the test, you should consider the following heuristics:
- Think of your previous experience about studying and see if it worked for you.
- If it worked for you, go for it.
- If it did not work for you, try a better solution this time.
Asking someone for date(or vice versa):
In deciding whether to go on a date with someone, the following heuristics should be kept in mind:
- Think that what you know about the person you are asked or being asked about the date
- Know what your own limits are
- Make sure you know the person well before asking for a date.
