Calculate the p-value for a Pearson Correlation Coefficient (r): In a study with 15 patients, the correlation coefficient between anesthesia dosage and heart rate decrease was calculated to be 0.55. Determine the p-value for this correlation coefficient using a two-tailed test at α = 0.05.Formula:Using a t-distribution for the correlation test:t = r n − 2 1 − r 2 Then use the t-distribution to find the p-value.What is the approximate p-value for this correlation?

In an anesthesia study with a p-value of 0.02 for a calculated odds ratio of 1.8, what does this suggest about the odds of an outcome?
