Refer to Data Set 2 in Appendix B and use the paired data consisting of the first and second columns of body temperatures for subjects who are initially standing. Based on the result, does there appear to be a correlation between temperatures in the initially standing postures and supine postures? If so, could researchers reduce their laboratory expenses by measuring only one of these two variables?
Use the rank correlation coefficient to test the claim of no correlation between the two variables. Use a significance level of α = 0.05.
