### Super Soaking Distance

1. 1. Capstone Project:<br />Renzo Gomez-Barrios<br />Edward Juarez<br />Miquela Tevis <br />Super Soaking Distance<br />
2. 2. Background<br />Does the brand of water gun and type of liquid used affect the distance traveled by the shot? <br />H0: τ0, τ1 ,τ2 ,τ3 = 0 where τ = average change in distance.<br />H1 : At least one τn≠ 0<br />
3. 3. The Water Guns<br />
4. 4. Summary of Plan/Analysis<br />Each water gun was fired in order with each liquid, changing the liquid after each one was shot.<br />Labeled tape on the floor in a straight line<br />Holding the gun parallel to the floor and aiming along the tape<br />Distance measured from nozzle to average landing point<br />
5. 5. Danger! Experiment in Progress!<br />
6. 6. Data Collection<br />Distance measured in inches<br />
7. 7. Results<br />Two-way ANOVA: Distance (in.) versus Guns, Liquid <br />S = 57.83 R-Sq = 64.70% R-Sq(adj) = 44.11%<br />
8. 8. Graphs<br />
9. 9. Decision/Answer<br />Reject the null hypothesis. <br />Based on our results the type of gun used is significant. However, the type of liquid used does not affect the distance traveled by a shot.<br />The results are based relative to each other, the p-value for the type of gun is higher than the p-value for the type of liquid.<br />Our results and answer could have been affected by the force with which the guns were fired, the change in angles that could have occurred and the measurements could have been slightly skewed.<br />
