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

For gold coins‚ soaking in very hot soapy water works the best. For old pennies‚ soak the coin in vinegar for at least 24 hours. For bronze coins — usually ancient coins — soak in distilled water (the minerals in tap water can further taint the coin’s surface if soaking for a long time) or olive oil — olive oil is a very gentle way to clean coins‚ but you may need to soak them for several weeks. Silver‚ copper‚ and nickel-clad coins can be soaked in distilled water or‚ to remove tough
