Daily Questions and Homework
Post Your Answers to the Daily Question(s) and homework here below the questions:
1. Did the true value for density fall within the confidence interval? What is the significance of the confidence interval with respect your experimentally measured density and the true value of density?
Yes, I am 90% confidence that Our expermental values are resentable.

2. Does the interval increase or decrease and as the confidence level changes from 90 to 95 to 99% and is the change intuitive? Could you explain the change to your students conceptually?
The interval increased because we have to make it bigger to be more sure that our data would fall where we thought it would.

3. The procedure for measuring density for the liquid used a graphical approach as opposed to our three trials and average method for determining the density of the solid. If you made a determinant (human) error for your first measurement in the liquid density portion, would this error plague or affect the subsequent measurements? (try to think of a situation where it would not and a situation where it would).
If I read the water level wrong it would affect the every test but if the mass is wrong on the first it would only affect only that first sample.
