Sarah is conducting a correlation analysis.  She creates a correlation matrix with 5 variables, using data from a sample of 37 people.  She changed her mind and decided to conduct her analysis as a two-tailed test with an alpha of .05.  What is the critical value for Sarah's correlation? Enter your value with four decimal places.  Do not include a zero to the left of the decimal (i.e., .0001, not 0.0001, not .01, not .001).
