Determining percent error: A student was supposed to measure 200.0 milliliters of water and obtained 196.0 milliliters instead. Her partner was supposed to measure 50.0 mL of water and obtained
48.0 mL instead. Determine who had the largest percent error in correct sig figs. The equation is shown.
Formula for % error= (measured -true)/ true x 100

Which part of a feedback mechanism is able to monitor the conditions outside of cells and usually uses nerve cells to relay this information to an intergrating center

Lab reagent, hypothesis test. a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl. these six measurements are assumed to be an srs of all possible measurements from solution. they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution. carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.

Which of the following are correct values for the ideal gas laws constant r
