Question
Please answer 9.4
92) Use these data based on seven samples from the sume population. What are your expectations about the probability of the F statistic? Table 9.2. Wing lengths in five houseflies randomly selected from a population with a parametric mean (u) of 45.5 and a parametric variance (o) of 15.21 Group 41 48 40 40 49 40 4 44 49 50 39 41 48 46 48 49 44 46 50 51 54 43 49 48 46 39 4744 4245 50 4142 51 42 9.3) Assume that a drug ("factor") was given to group 5 that increased the wing length by 7 units. 9.4) Redo analysis 9.3 assuming that an environmental "factor" affected group 1 that decreased the wing length by 7 units. Now both group I and 5 have been affected (group 1 decreased by 7 units; group 5 increased by 7 units). 9.5) Redo analysis 9.4 by decreasing each of the values in group 2 by a random "factor" for cacih value (eg., subtract 3 from first individual, I from second individual, etc.). Now groups, 1,2 and 5 have been affected by different factors. 9.6) Analyze the following data using both ANOVA and Kruskal-Wallis procedures of response times (msec) for individuals of different ages.
