What assumptions are necessary to ensure the validity ror? Use = .05. =.05. of the inferences made in parts b, c, and d? 9.53 Suppose an experiment employing a randomized block design has four treatments and nine blocks, for a total of4x 9 36 observations Assume that the Total Sum of Squares for the response is SS(Total) =500. For each of the following parti- tions of SS(Total), test the null hypothesis that the treatment means are equal and test the null hypothesis that the block means are equal. Use .05 for each test. a. The Sum of Squares for Treatments (SST) is 20% of SS(Total), and the Sum of Squares for Blocks (SSB) is b, SST is 50% of SS(Total), and SSB is 20% of C. SST is 20% of SS(Total), and SSB is 50% of d. SST is 40% of SS(Total), and SSB is 40% of e. SST is 20% of SS(Total), and SSB is 20% of 30% of SS(Total). SS(Total). SS(Total). SS(Total) SS(Total). Applying the Concepts-Basic 9.54 Making high-stakes insurance decisions. Refer to the W Journal of Economic Psychology (Sep. 2008) study on high-stakes insurance decisions, Exercise 9.26 (p. 520). A second experiment involved only the group 2 subjects. In part A of the experiment, these 84 subjects were informed of the hazards (both fire and thft) of painting hut

Explanation / Answer

Question 9.50)

a) there are 3 blocks and 5 treatments

b) 15 observations were collected in experiments ( since df for sst = n-1 therefore n = 15)

c)Ho : There is no difference between the treatments

Ha : At least one treatment differs significantly

d) F statistic = 9.109 should be used
