  1. if the p-value is greater than 0.1, we generally conclude the data are consistent with the null hypothesis: true<\/li>\n\n\n\n
  2. what is the best way to characterize the random error present in a measurement?: take replicate measurements of your analytes and using the standard
    deviation and a t-table specify an error bar with a confidence limit<\/li>\n\n\n\n
  3. statistical interference assesses whether an observed phenomenon in the
    data can reasonably be attributed to chance or not: true<\/li>\n\n\n\n
  4. suppose we collected a sample size n = 100 from some population and
    used the data to calculate a 95% confidence interval for the population meannow suppose we are going to increase the sample size to n = 300. keeping<\/li>\n<\/ol>\n\n\n\n

    all else constant, which of the following would we expect to occur as a resultof increasing the sample size?: (1) the standard error would decrease, (2) the
    margin of error would decrease<\/p>\n\n\n\n

      \n
    1. in designing a clinical trial where each subject receives both a placebo anda proposed treatment, what statistical test would be most appropriate?: pairedt-test<\/li>\n\n\n\n
    2. an atomic absorption analysis is to be done on the calcium in a sample
      of powdered milk. a 12.55 gram sample of the powder is wet ashed in nitric
      acid and diluted to 50.00 mL with distilled water. a 1.00 mL aliquot of this
      is transferred to a 50.00 mL solution using EDTA. using a wavelength of
      422.6 nm in an atomic absorption experiment, this diluted sample showed anabsorbance of 0.375. a standard calcium sample (treated the same way) witha known concentration of 20.0 ppm provided an absorbance of 0.859. what isthe ppm of calcium in the powdered milk?: 437 ppm<\/li>\n\n\n\n
    3. in a 3 step serial dilution: the first dilution is 1\/10, the second dilution is 1\/5and the third dilution is 1\/4. what is the total dilution factor of this 3 step seria<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
