These are problems from the text that were advised to study for the next exam.
1) Determine the values of r for which det(A-rI) = 0
2) Verify that X(t) is a fundamental matrix for the given system and compute X-1(t). Use the result, x' = Ax, x(t0) = x0 to find the solution to the given initial value problem.
3) Using matrix algebra techniques, find a general solution of the system.
4) Find the solution to the given system that satisfies the given initial condition.
5) Find the solution to the given system that satisfies the given initial condition.
The mathematics SAT scores of the seven students in a mathematics seminar are 533, 553, 578, 586, 619, 626, and 633. Suppose that the student with the score of 533 drops the seminar and is replaced by a student with a score of 765.
The weights of canned hams processed at Henline Ham Company follow the normal distribution, with a mean of 9.20 pounds and a standard deviation of .25 pounds. The label weight is given as 9.00 pounds
Discuss an example where you would use a test of hypothesis with three or more population means (that can be analyzed using ANOVA technique) at your employment or personal life.
Construction of confidence interval for difference between first and second sample mean revealed interval to be 10 plus or minus 12. We conclude.

On a test whose distribution is approximately normal with a mean of 50 and a standard deviation of 10, the results for three students were reported as follows:
Determining sample-size is important step when planning a statistical study. It is also quite a difficult task since many variables must be considered.
Suppose that f, g, h are three functions defined on (a, b) and c (a, b). Assume that f and h are differentiable at c, f(c) = h(c), and f(x) g(x) h(x) for all x (a, b).
