Scores on the GRE. A college senior who took the Graduate Record Examination exam scored 580 on the Verbal Reasoning section and 650 on the Quantitative Reasoning section. The mean score for Verbal Reasoning section was 459 with a standard deviation of 114, and the mean score for the Quantitative Reasoning was 432 with a standard deviation of 148. Suppose that both distributions are nearly normal. Round calculated answers to 4 decimal places unless directed otherwise.
1.Write down the short-hand for these two normal distributions.
The Verbal Reasoning section has a distribution N( , )
The Quantitative Reasoning section has a distribution of N( , )

C. Quantitative Reasoning
5. What is her percentile score on the Verbal Reasoning section? Round to nearest whole number.
6. What is her percentile score on the Quantitative Reasoning section? Round to nearest whole number.
7. What percent of the test takers did better than she did on the Verbal Reasoning section? %
8. What percent of the test takers did better than she did on the Quantitative Reasoning section? %
9. What is the score of a student who scored in the 71th71th percentile on the Quantitative Reasoning section? Round to the nearest integer.

Please show all the steps in detail, along with all the codes
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?
