Question: You will need sample means and sample variances for each of the groups. These are: Urban: Mean = 83F; Variance = 3.8, N = 8

You will need sample means and sample variances for each of the groups. These are:

Urban: Mean = 83F; Variance = 3.8, N = 8

Grassland: Mean = 75F; Variance = 2.5, N= 5 Forest: Mean = 68F; Variance = 1.4; N = 6

Wetland: Mean = 72F; Variance= 1.5; N = 3

  1. Using the data above, perform an ANOVA to determine if there are significant differences between the groups. Use the significance levels: 0.05 and 0.01.
  2. What is your sampling distribution for this test?
  3. What are your degrees of freedom? (Find both DF1 and DF2)
  4. What are your F-critical values [at 5% and 1% levels]?
  5. What is your calculated F-value (F-ratio)?
