Question
  1. Compute for the F – Test – Single Factor ANOVA, an agronomist planted three test plots each with four varieties of wheat and obtained the following yields (in pounds per plot):

Variety A:

65

64

60

Variety B:

55

56

63

Variety C:

56

59

59

Variety D:

62

59

63

 

  • Calculate n . s    for these data, the mean of the variances of the four samples and the value of F.
  • Assuming that these data constitute random samples from four normal populations with the same standard deviation, test at the 0.01 level of significance whether the differences among the four sample means can be attributed to chance.
