Question

B) CRITICAL VALUES

C) Is there sufficient evidence to conclude that there is a linear correlation between the two​ variables?

The data below shows the selling price (in hundred thousands) and the list price (in hundred thousands) of homes sold. Answer parts a-c. Selling Price (x) List Price (y) 400 410 303 317 380 385 430 440 455 485 480 477 318 320 354 370 416 431 333 342 Click here to view a table of critical values for the correlation coefficient. a. Find the value of the linear correlation coefficient r. r= .989 (Round to three decimal places as needed.) b. Find the critical values of r from the table showing the critical values for the Pearson correlation coefficient using a = 0.05. The critical values are + 1. (Round to three decimal places as needed.)

Answer 1

Solution :

Given that ,

n = 10

df = 10 -2 = 8

$\alpha$ / 2 = 0.025

Critical value = $\pm$ 0.632
