Question

Random sampling from four normally distributed populations produced the following data: (image)

a. Calculate the grand mean. (Negative value should be indicated by a minus sign. Round your answer to 2 decimal places.)

b. Calculate SSTR and MSTR. (Round intermediate calculations to at least 4 decimal places and final answers to 4 decimal places.)

c. Calculate SSE and MSE. (Round intermediate calculations to at least 4 decimal places and final answers to 4 decimal places.)

e-1. Calculate the value of the F(df1, df2) test statistic. (Round intermediate calculations to at least 4 decimal places and final answer to 3 decimal places.)

e-2. Find the p-value. (which one)

  • 0.05 ≤ p-value < 0.10
  • p-value ≥ 0.10
  • 0.01 ≤ p-value < 0.025
  • p-value < 0.01
  • 0.025 ≤ p-value < 0.05
