Question 2

The Russet Potato Company has been working on the development of a new potato seed that is hoped to be an improvement over the existing seed that is being used.
 
  Specifically, the company hopes that the new seed will result in less variability in individual potato length than the existing seed without reducing the mean length. To test whether this is the case, a sample of each seed is used to grow potatoes to maturity. The following information is given:Old Seed New SeedNumber of Seeds = 11 Number of Seeds = 16Average length = 6.25 inches Average length = 5.95 inchesStandard Deviation = 1.0 inches Standard Deviation = 0.80 inchesThe on these data, if the hypothesis test is conducted using a 0.05 level of significance, the calculated test statistic is:A) = 1.25
  B) = 0.80
  C) = 0.64
  D) = 1.56
