with acetic acid to produce a short amount of electricity. Even though it only conducts a small amount of voltage‚ we investigated and experimented on how it can produce more than usual without adding any other components on the project except zinc‚ copper‚ vinegar‚ or a unique container that can increase the voltage of our product. The zinc can produce electricity because of the chemical reaction it occurs when it is soaked in vinegar’s acetic acid‚ the zinc is dissolved to produce hydrogen gas; while

There are 18 data sets that accompany the text book. These data sets can be found when you enter StatCrunch from the course. Here is a list of the data sets and the variables found in those data sets. If there is no listing of variables then they are easily identified in the data set. Data Set 1: Health Exam Results (both male and female) AGE is in years‚ HT is height (inches)‚ WT is weight (pounds)‚ WAIST is circumference (cm)‚ PULSE is pulse rate (beats per minute)‚ SYS is systolic blood pressure
