A team of researchers wants to know if the bait used in the trap (scent. sugar or a chemical} inuences the number of spruce moths that are caught in the trap. The researchers used t] traps (all the same brand} and randomly assigned them to a different bait. Use the Minitab output provided to answer the following questions. One-way ANOVA: Scent, Sugar, Chemical Method Null hypothesis All means are equal Alternative hypothesis Not all means are equal Significance level 0 = 0.05 Equal variances were assumed for the analysis Factor Information Factor Levels Values Factor 3 Scent, Sugar, Chemical Analysis of Variance Source DF Adj $5 Adj MS F-Value P-Value Factor 2 113.0 56.52 0.63 0.537 Error 57 5130.0 90.00 Total 59 5243.0 Model Summary S R-sq R-sq(adj) R-sq(pred) 9.48679 2.16% 0.00% 0.00% Means Factor N Mean StDev 95% CI Scent 20 24.75 10.29 (20.50, 29.00] Sugar 20 27.80 9/06 (23.55, 32 05) Chemical 20 27.50 9.06 (23.25, 31.75) Pooled StDev = 9.45679What is the response variable? Select one: O a. Moths O b. Number of moths caught O c. Bait type O d. Brand of trap What is the explanatory variable? Select one: O a. Moths O b. Number of moths caught O c. Bait type O d. Brand of trap How many levels does the explanatory variable have? Answer:What are the levels of the explanatory variable? 1 A v B E S State the appropriate hypotheses (Ho and Ha). 1 Av B SS PAWhich of the following is the correct denition of the parameter in ? Select one: O a. Where p. represents the mean number of spruce moths caught on one of the traps. for this population model of moths. O b. Where u. represents the mean number of spruce moths caught if the trap had a scent, for this population model of moths. O c. Where p1 represents the mean number of spruce moths caught if the trap was scented. sugar or chemical, for this population model of moths. Cl d. Where It. represents the mean number of spruce moths caught in scent traps, for the moths caught. Identify the values of the test statistic and P-tralue from the Minitab output. State your conclusion in the context of the problem. 1 B I E SS Would it be appropriate to run multiple comparison test (i.e. Tukey) to see which Bait has an effect on the number of moths caught in the trap? Yes * since we concluded Ho
