What Does Not Support The Null Hypothesis
The results of the statistical test did not support the hypothesis. The statistical test proves that the null hypothesis can be accepted regarding temperature impacting weight. However, we accept the hypothesis regarding conductivity. The test shows that the conductivity of a cell submerged in a solution can be altered with changes in temperature as the independent variable. However, the test shows that we accept the null hypothesis for weight change because weight is not impacted by temperature. The statistical test used results that did not show that the lipid bilayer portion of the membrane of living cells is not permeable like the dialysis membrane used in the lab. The dialysis membrane used in the lab is permeable to small ions like Na+ and Clˉ. The experiment was also performed in a “closed system” which is not reflected in the statistical test. The results of the statistical test does however support our hypothesis because it shows that as water is moving into the cell constantly while salt is leaving the cell. There was an average weight change of 0.00042379 and 0.000407908 and an average conductivity change of 0.320388434 and 0.40975815. The conductivity change matches the

Our results do not support our hypothesis when it says that temperature impacts cell weight. Our hypothesis states that when temperature increases the rate of osmosis also increases. The cell weight increases with water and the conductivity increases because of the salt leaving the cell. The results of the data proved to support the hypothesis because the concentration of sodium increased outside the cell. Our hypothesis also states that when the temperature of a solution decreases it slows down the rate of osmosis. The cell weight would increase with water equally in both colder and warmer temperatures. The conductivity would increase but at a slower rate than it would increase in a warmer
