- Which statement is true? Question 12 options: Precision is measured by standard deviation. Precision is measured by error or relative error. Accuracy is measured by the standard deviation.Please answer this question as fast as you can please and tahnk you. I will afterwards write an wonderful review on solving the question. Thank you. You determined experimentally the density of a solution in triplicate. Considering the results what is the standard deviation of your results? Answer your question with the correct number of significant figures. The answer should be in units of g/mL Trial 1: 0.9991 g/mL Trial 2: 0.9984 g/mL Trial 3: 0.9996 g/mLDetermine the Average Mass and the Standard Deviation for the following data: Mass of pennies in grams = 1.5021, 1.4736, 1.4966, 1.5164, 1.5420, 1.4699 g. Average Mass grams +/- Standard Deviation grams
- A piece of metal was weighed on a laboratory balance four times and gave the following results: 15.75, 15.72, 15.79, and 15.76 g. Determine the average mass and the standard deviation.Consider the following sets of replicate measurements: (1) Calculate the mean and standard deviation of Group A. (2) Determine the confidence interval at 95% confidence level. Assume the data here are the only knowledge you have and no previous measurements are available.There are three types of error in the laboratory: random error, systematic error, and gross error. Elaborate how can you use standard deviation and percent error in identifying the errors made in the measurement.
- 3) For the results, discuss the significance of the following in terms of accuracy or precision: a) Deviation vs Absolute Error. b) % Error vs Standard Deviation.Suppose a student completes an experiment with an average value of 2.9 mL and a calculated standard deviation of 0.66 mL. What is the maximum value within a 1 SD range of the average?The accepted density of Manning is 18.00g/mL. Your lab team measures the density of Manning to be 19.00g/mL. What is your percent error?
- Question 3 Does standard deviation give a measure of precision or accuracy? Use the editor to format your answer2. A study of body mass index (BMI) in adults showed that for men aged 40–44, the mean BMI level is 26.7 with a standard deviation of 3.7. Assuming a normal distribution, what percentage of men in this age group have a BMI between 30.0 and 35.0?1. Determine the average and standard deviation for the following set of numbers. 45.6g, 52.1g, and 53.8g
