The data below shows the selling price (in hundred thousands) and the list price (in hundred thousands) of homes sold. construct a scatterplot, find the value of the linear correlation coefficient r, and find the p-value using alphaαequals=0.050.05. is there sufficient evidence to conclude that there is a linear correlation between the two variables?

The answer would be -3.9> -4.5

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
