Isolation Score: 45, 37, 22, 15, 39
1, The correlation coefficient between the variables
equals
2, Use the t test for the correlation coefficient, for the 95%
confidence, the critical t value equals .
3, The test t value equals .
4, The p value equals .
5, Is there a significant relationship between the variables?
(answer "Yes" or "No")
6, Is it necessary to do a regression analysis? (answer "Yes" or
"No")
