Hi you have posted multiple question in one time. As per the guidelines I am obliged to answer first question only. The scatter plot of the data can be drawn as:From the scatter plot it can be seen that there seems to be negative relation between x and y because as the x is increasing the y - is decreasing . So, correlation coefficient to be negative.
