treatment groups (no fertilizer, liquid fertilizer, pellet fertilizer) in a class monitored and recorded the hat it took until they could perform the first pruning for their basil plant. SPSS output containing he number of days required is provided for the LIQUID group and the PELLET groups below. Perform a t samples t test to determine if there is a significant difference between the days to first pruning in the d pellet fertilizer groups. Let a = 5%. TMENT N Mean Std. Deviation S.E.
