部分真題預(yù)覽：

Part A： 1）A certain state’s education commissioner released a new report card for all the public schools in that state. This report card provides a new tool for comparing schools across the state. One of the key measures that can be computed from the report card is the student-to-teacher ratio, which is the number of students enrolled in a given school divided by the number of teachers at that school. The data below give the student-to-teacher ratio at the 10 schools with the highest proportion of students meeting the state reading standards in the third grade and at the 10 schools with the lowest proportion of students meeting the state reading standards in the third grade.

Ratios in the 10 Schools
with Highest Proportion of Students Meeting Standards

Ratios in the 10 Schools
with Lowest Proportion of Students Meeting Standards

1. Display a dotplot for each group to compare the distribution of student-to-teacher ratios in the top 10 schools with the distribution in the bottom 10 schools. Comment on the similarities and differences between the two distributions.
2. Any statistical test that is used to determine whether the mean student-to-teacher ratio is the same for the top 10 schools as it is for the bottom 10 schools would be inappropriate. Explain why in a few sentences.

Part B： 6) The nerves that supply sensation to the front portion of a person’s foot run between the long bones of the foot. Tight-fitting shoes can squeeze these nerves between the bones, causing pain when the nerves swell. This condition is called Morton’s neuroma. Because most people have a dominant foot, muscular development is not the same in both feet. People who have Morton’s neuroma may have the condition in only one foot or they may have it in both feet.

Investigators selected a random sample of 12 adult female patients with Morton’s neuroma to study this disease further. The data below are measurements of nerve swelling as recorded by a physician. A value of 1.0 is considered “normal,” and 2.0 is considered extreme swelling. The population distribution of the swelling measurements is approximately normal for adult females who have Morton’s neuroma.
