1. Sample question: Calculate an independent samples t test for the following data sets:
Data set A: 1,2,2,3,3,4,4,5,5,6
Data set B: 1,2,4,5,5,5,6,6,7,9
2. Using the following data perform a significance test to compare the means of strains A and B
and comment on the results obtained.
Strain A: Ex = 281 mn, n=10,
Ex'= 8854.0
Σ= 9482.0
Strain B: Ex=272 mn, n= 8,
3. With the help a suitable test find out the significant differences between two samples.
