Two lab sections were required to determine the amount of zinc in a multivitamin. The first lab section with 16 students reported an average value with a s of 1.86. The second lab section with 13 students reported an average value with a standard deviation of 1.43. Is the difference in standard deviations signi confidence level? Refer to Table 43 for critical values of F. Variation of lab 1=1.862=3.4596 Variation of lab 2=1.432=2.0449 F calculated = Variance of lab1/ Variance of lab 2=3.4596/2.0449=1.6918 Two lab sections were required to determine the amount of zinc in a multivitamin.
