Consider Dataset D for answering the questions that follows below.

The median marks for Course X and Y for the past 8 semesters were given on the dataset. Determine the strength of relationship between Course X and Course Y by calculating the correlation coefficient between them. What can you say about their relationship?

Calculate the regression line that best explain the relationship between the dependent variable Course Y and independent variable course X.

Estimate the most likely value for Course Y given the mean value of Course X.

	CourseX	CourseY

1	90	84
2	94	75
3	91	73
4	91	86
5	85	76
6	85	91
7	93	84
8	86	81

Let D(x, y) be the predicate defined on natural numbers x and y as follows: D(x, y) is true whenever y divides x, otherwise it is false. Additionally, D(x, 0) is false no matter what x is (since dividing by zero is a no-no!). Let P(x) be the predicate defined on natural numbers that is true if and only if x is a prime number. 1. Write P(x) as a predicate formula involving quantifiers, logical connectives, and the predicate D(x,...
