Probability and Statistics for Engineering and the
Sciences Seventh Edition by Jay Devore
Buy the version without MINITAB. We will not use MINITAB in the course.
You can use the Sixth Edition but it will be a little harder because
some of the homework problems have different numbers in the two editions.

The first midterm will be in
lecture on October 7 and the second midterm will be in lecture on November 11.
The final exam is on Friday, December 19 from 1:30 to 3:30.
There will be no makeup for the final exam except in case of medical emergency, family medical emergency
or university related absence.
Homework 10 (due November 24)
Some more problems from Chapter 6.
Section 6.1 – 7,8,10
Section 6.2 - 25(a), (use the results from Example 6.17)
Problems on Random Intervals
1. Suppose X has normal distribution with mean 5 and variance 1. Find
the probability that 5 will be in the random interval (X-1,X+1).
2. Suppose that X has uniform distribution on the interval [0,1].
Find the probability that 1/2 will be in the random interval (X - 1/4, X +
1/4).
3. Suppose X has normal distribution with mean 5 and variance 1. Find the
probability that the random variable 2X will be in the random interval (X-1,X+1).
Homework 11 (due December 8)
Problems on Confidence Intervals
Section 7.1 - the z-intervals (use these formulas if you know σ)
Section 7.1 - 5,6,7,8 (this is about asymmetric
two-sided intervals. The interval in
(7.5) is the symmetric one of confidence level α),
9 (this problem is about one-sided
intervals, I will develop the general theory in class).
Section 7.3 - the t-intervals (use these formulas if you don't know σ)
Section 7.3 - 32, 33(c), 37(a),(b), 40(c)
To do 37(a),(b) you need to extract the following information from the MINITAB
outputs
sample mean ( x bar) = Mean = 0.9255
sample variance (s) = St Dv = .0809
sample variance/ √n = SEMean = .0181
To do 40(c) you will need to look up the
formula for the two-sided prediction interval in the Proposition on page 274
and write down the corresponding upper-tailed prediction interval (hint: change
α/2 to α). Use the MINITAB output from Section 7.2 - 17 and the above
formulas.
COURSE DESCRIPTION
We will cover the
following topics in the order given..
1. All of Chapter 2.
2. All of Chapter 3
3. All of Chapter 4 except for
the last two sections.
4. All of Chapter 5 but very little multiple
integrals.
5. Random Samples (from handout) .
6. Some of Chapter 6 on point estimation.
7. Random intervals (from handout).
8. Some of Chapter 7 on interval estimations.
9. Moment generating functions (from handout).
Your course grade will be determined from the following using a curve.
Test #1 50 points
Test #2 50 points
Homework 50 points
Final exam 100 points
Total 250
points
If you get 125 points or more you will get at worst a C. If you get
less than 125 points you
will get an F.
Your homework grade.
Homework will be assigned at the Tuesday lecture and must be handed in at your
TA section by he following Monday. Usually, you can
either hand in your homework at your TA section or else put in an envelope
outside your TA's office BEFORE 6:30 ON MONDAY.
