Extracted text: An AUDIO tutorial is available for this problem. Low concentrations of Ni-EDTA near the detection limit gave the following counts in a mass spectral measurement: 172, 124, 124, 148, 196, 190., 196, 165, 114, 145. Ten measurements of a blank had a mean of 45 counts. A sample containing 1.00 µM Ni-EDTA gave 1797 counts. (a) Find the mean. 4.0 counts (b) Find the standard deviation. 4.0 counts (c) Estimate the detection limit for Ni-EDTA. 4.0 counts 4.0 M
