Bivariate numerical data

### Consider binary strings with n digits (for example, if n=4, some of the possible strings are 0011,1010,1101, etc.) Let Zn be the number of binary strings of length n that do not contain the substring 000 Find a recurrence relation for Zn You are not required to find a closed form for this recurrence.

### What is the correlation coefficient and what is its significance? Explain why correlation coefficient is bound between -1 and 1. How correlation coefficient depicts itself in scatterplots? Aside from probabilistic models, explain what is least squares line fitting.

Bivariate numerical data

### Suppose that, for a sample of pairs of observations from two variables, the linear correlation coefficient, r , is negative. Does this result necessarily imply that the variables are negatively linearly correlated?
