Note: HQ is defined as an oil characterized as “High quality”; LG is defined as an oil characterized as “Lower grade”. * If the F-Test Two Sample for Variances ratio of F:F crit. one-tail is greater than 1, then the sample populations are unequal. ^ If the t-Test: Two-Sample Assuming Unequal/Equal Variances ratio of t-Stat:t crit. two-tail is greater than 1, then the observed difference in sample mean is significant. # If the ANOVA: Sing Factor ratio of F:F-crit. is greater than 1, then the sample cohorts are considered different. The α (significance level) used to obtain all the critical values was 0.05.
