Triglycerides were lower on the first measure b. There is a significant difference between the first and second measures of triglycerides c. Their is a moderate positive correlation between the first and second measures of triglycerides. d. The confidence interval is wide, indicating clinical significance.

Explanation / Answer

Answer is (c) there is a moderate positive correlation between first and second measure of triglycerides

Note : since the p value for correlation coefficient is 0.001(less than 0.05) which implies the result is significant, there is correlation between two measures, also the correlation is positive, and it is 0.592 , which implies moderate correlation

( a) is not correct as we can see measure #1 > measure #2

(b) is not correct as we can see the p value is greater than 0.05

( d ) is not correct as confidence interval includes 0 , difference is not significant
