1. Seedling emergence example
For this question you will need to analyze data given in le seedEmergence. For your convenience, the
data is posted as a text le.
5 seed disinfectant treatments were applied to several agricultural plots, where 100 seeds were planted in
each plot. The response variable is \plants that emerged in each plot". The goal is to compare these 5
treatments using certain appropriate number of blocking levels which could be decided by looking at the
data.
(a) Use graphical (eg, boxplots) and numerical methods(group means, sd etc) to describe the dierences
in treatments.
(b) What statistical model would you use to analyze this data? Explain.
(c) Construct the analysis of variance table for this problem.
(d) Using alpha=0.05, is there any evidence that the treatments dier with respect to emerging plants in
each plot?
(e) Give estimates of "all" the parameters in the model.
(f) Analyze the residuals from this experiment. Which assumptions about the model are satised and
which are not?

The production department of Celltronics International wants to explore the relationship between the number of employees who assemble a subassembly and the number produced. As an experiment, 3 employees were assigned to assemble the subassemblies. They produced 12 during a one-hour period. Then 5 employees assembled them. They produced 20 during a one-hour period. The complete set of paired observations follows. |
| Number of Assemblers |
One-Hour Production (units) |
| 3 | 12 |
| 5 | 20 |
| 2 | 6 |
| 6 | 25 |
| 4 | 17 |
|
The dependent variable is production; that is, it is assumed that different levels of production result from a different number of employees. |
