A neuropsychologist was interested in how Monkeys learn to perform a task. The task was to retrieve a coconut from the opposite side of a river. 15 wild monkeys were assigned to one of three conditions where they were shown how to retrieve a coconut by using one of three different techniques. The times taken for the monkeys to retrieve the coconut is given below in minutes. Perform an ANOVA hypothesis test to answer the question: Are there significant differences in the speed of coconut retrieval between the 3 techniques? Present your answers with an ANOVA table and follow the full hypothesis testing procedure as presented. The results are recorded in the following table. Technique 1 Technique 2 Technique 3 15 13 13 13 6 Means 7 11 St-Dev 6 3.8079 Ho: Average times to retrieve a coconut are the same. H1: Average time for at least one technique is different from the others. (a) Complete the ANOVA table. Use a=0.05 significance level. (Round the SS and Variance values to 2 decimal places and F-test-statistic to 1 decimal place. Leave no cells blank) Sums of Squares (SS) DF Variance F-test Source of Variation (Round ans to 2 dp] Answer use 2 dip(Answer use 1 Op Between Groups 43.3233 Within Groups Total 14 (9 marks) (b) Look up the critical value from tables to answer the question below. There are v in the retrieval time for the techniques
