The question that we would like to answer is “Do students who learn English and another language simultaneously score worse on the SAT Critical Reading Test? The mean score of the general population among all test takers is 501. A random sample of 100 test takers who have learned English and another language simultaneously had a mean score of 485, with a standard deviation of 116. Do the results suggest that the simultaneous learners score worse on the SAT Critical Reading Test?
a) State the null and alternate hypotheses.
b) Perform a test using t-distribution. Show the results
c) At .1 level of significance test your hypotheses and state your conclusion.

3. We would like to know whether, on average, students learn
better in a self-paced or in an instructor-paced computer
learning environment. We randomly assigned 40 BL131 students to
self-paced sessions and a different 40 students to an
instructor-paced sessions for one unit and recorded the exam scores
for that unit. The two-sided p-value for the comparison was 0.01.
alpha = 0.05.

You would like to determine who in a group of 100 students
carries antibodies for a certain virus. You can perform blood tests
on each student individually, which would require 100 tests.
Instead, you can partition the students into 10 groups of 10.
Combine the blood samples of the 10 students in each group, and
analyze the combined sample. If none of the 10 students in that
group carries the antibodies, the test will show negative, while if
one or...

I am a graduate student in mathematics who would like to learn
some classical mechanics. However, there is one caveat: I am not

think of the fields that arise in physics as sections of vector
bundles (or maybe principal bundles) and would love an approach to
classical mechanics or what have you that took advantage of
this.
Now for the questions:
Is there a text book you would recommend that...
