Final answer:
To determine the mean, standard deviation, and 95% confidence interval for a calculated mass of acid, one would need the sample mean, the standard deviation, and use the relevant z-score to compute the confidence interval range.
Step-by-step explanation:
The question asks about how to calculate the mean, standard deviation, and 95% confidence interval of a calculated mass of the acid. These are statistical concepts used to analyze and interpret data. The mean is the average of a dataset, and the standard deviation measures the spread of the data points around the mean. A 95% confidence interval provides a range of values that we can be 95% certain contains the true population mean. In practice, to calculate this interval, we would need the sample mean, the population standard deviation (or an estimate from the sample if the population standard deviation is unknown), and we would use the z-score associated with a 95% confidence level from the standard normal distribution. For instance, if a sample mean is 10 and we have a known standard deviation, we would calculate the margin of error (EBM), and construct the interval accordingly, as seen in the provided examples for different confidence levels.
