- based on the data from the experiment, how do i calculate the percentage of error? also, how do i explain about the observation.What impact would using a much smaller sample have on the accuracy of your resultsWhat are the differences between systematic and random errors and how do they effect accuracy and precision? In what circumstances would you use standard addition (versus a normal calibration curve) to determine the amount of an analyte in a sample? A urine sample, containing analyte Z is analysed by the standard addition method where 5 mL of the original sample was mixed with increasing amounts of a Z standard and each solution diluted to a volume of 50 mL prior to analysis. A plot of the final concentration of the standard in each of the 50 mL samples (x axis) versus The measured signal from the analysis of each 50 mL sample (on y axis) produced a straight line with the general equation: y = 44.72x + 4.06 what was the final concentration of Z in the 50 mL standard addition sample? what was the initial concentration of Z in the original urine sample?
- In a particular trial, a student got a value for R of 0.083. Calculate the percent deviation of this result. Enter a number without the % sign. The percent deviation should be reported as a positive value.True or false.20,18,2,4,15,15,10 Using these data, construct a 80% confidence interval for the average net change in a student's score after completing the course. Assume the population is approximately normal. Construct the 80% confidence interval. Round your answer to one decimal place.
- Student A determines the percent acetic acid in their sample to be 4.31% and they report a standard deviation of 0.57. Student B also reports a value of 4.31 % acetic acid, with a standard deviation of 1.2. Which student (A or B) has the more reliable determination? Briefly, 1 - 2 sentences,kindly help me calculate the % error of the dataUse the calibration curve or linear regression equation to determine the concentration of FD&C blue dye No. 1 in Kool-aid.
