Suppose you computed r 0 817 using n 13 data points Using the critical values table below determine if the value of r is significant or not df CV and df 1 0 997 11 2 0 950 3 0 878 4 0 811 5 0 754 6 0 707 0 666 0 632 0 602 0 576 7 8 9 10 12 13 14 15 16 17 18 19 20 CV and 0 555 Select the correct answer below 0 532 0 514 0 497 0 482 0 468 0 456 0 444 0 433 0 423 r is significant because it is between the positive and negative critical values r is not significant because it is between the positive and negative critical values r is significant because it is not between the positive and negative critical values r is not significant because it is not between the positive and negative critical values df CV and 21 0 413 0 404 0 396 0 388 0 381 0 374 0 367 0 361 0 355 0 349 22 23 24 25 26 27 28 29 30 df 40 50 60 70 80 90 100 CV an 0 304 0 273 0 250 0 232 0 217 0 205 0 195
