Stat 215 Assignment 19 Module: HypTest_mu1_mu2 , Exercise: Biomass Objective : (not available) Problem Description : A research biologist hypothesized that a north-facing slope (cool and moist site) is different than a sunnier south-facing slope (warm and dry site) in terms of productivity. To validate his claim the biologist randomly selected 30 sites on north-facing slopes and calculated above ground biomass (dry weight of leaves and stems of plants) at each site. He also randomly selected 28 sites on south-facing slopes and calculated the above ground biomass at each site. Click here to see the north-facing and the south-facing biomass data. The Histogram Java applet displays the biomass values for south and north slopes in a histogram coplot. The KSample Java applet displays the biomass values for south and north slopes in a dotplot. Question What are the assumptions underlying the two-sample t-test? Answer
