1. we calculated that the density for our sample to be 2.79. We believe our metal was Aluminum since the density of Al is 2.698. the actual density does fall within the 90% and 95% confidence level. the significance of this allows us to ascertain identify unknown solid samples
2. the increase in confidence interval can cause an increase in the possible density values.
3. Human error in measurements can have a adverse affect of results...if limited test are run... but with a high number of test being performed a human error in measurement would probably not have much affect. An error might carry on to all the measurements or it may not affect it at all.
4. the calculated value of our bulb was 68.12 watts.
5. In teaching science in grades 8 through 12 and with our science department requiring Science Fair projects. I have used excel quite a bit for designing graphs and tables. I have my physics and physical science students graph all types of motion. I have used motion detectors some with the CBL and CBR.
