A set of samples from an abandoned industrial site detected a suspected groundwater contaminant at a mean concentration of 0.045 µg/L with a standard deviation of 0.007 µg/L. How many samples are required to be collected at a confidence level of 95% and power of 90% if the mean background concentration of the contaminant is 0.035 µg/L? О А.З О В. 4 С. 5 O D. 6
A young researcher was evaluating a standard method for determining the methylmercury content in blue fin tuna using high performance liquid chromatography (HPLC). She determined the standard deviation (?)(s) for the method to be 0.440.44 ppb and assumed that ?s was a good approximation of ?σ . As a test, she used this method to evaluate the methylmercury content in a National Institutes of Standards and Technology (NIST) standard and determined the unknown amount to be within 0.210.21 ppb (?)(μ) of the known mean with 99% probability. How many replicate measurements of the NIST standard did the researcher perform?

20 To determine the organic material in a dried lake bed, the percent carbon by mass is measured at two different locations. To compare the means of the two different locations, it must first be determined whether the standard deviations of the two locations are different. For each location, calculate the standard deviation and report it with two significant figures. location 1 standard deviation: location 2 standard deviation: What is the calculated F value for comparing the standard deviations? Fcale = no Sample 1 2 3 4 5 Are the standard deviations for the two locations significantly different at the 95% confidence level?

An ore sample was analyzed for its Fe content. Student A analyzed the sample a total of six times and her results had a standard deviation of 1.33. The same sample was analyzed five times by Student B and his results had a standard deviation of 3.42. To determine if their standard deviations are similar, they perform an F test. The calculated F value is and the table value of Fis 3 in your book for critical values of F. O 6.61; 7.39 O 6.61; 9.36 O 0.151; 9.36 O 2.57; 7.39 O 6.61; 6.98 Refer to Table 4-
