The following problems reflect the reading material you had to prepare for this week. From the list below, choose one problem, write it down, and solve it in detail (show all of your steps). You should pick a problem that has not yet been attempted if you can. Please label your solution with the corresponding question number. In your solutions, you are only to use the math concepts that have been covered in this course up to this point.
Respond to at least two of your classmates posts. Responses to your peers must be substantive and should critique their solutions to help them correct or improve their work. Do not solve the problem for them if they have posted incorrect work. Replies to your professor that are required to correct or clarify your work do not count towards the requirement of two replies. If your professor asks a question directed to the entire class, answers to that question count towards your reply requirement.
You must participate in the forum on at least two days.
Your other replies should attempt to discuss the problem. Here are some suggestions:
a) Discuss what you learned from the problem.
b) Discuss something the problem made you think about.
c) If we were to change the problem slightly, address how the answer would change.
See the syllabus for complete grading information
1) A test consists of 60 multiple choice questions, each with four possible answers, only one of which is correct. A student randomly guesses at all 60 questions.
a) Find the mean and the standard deviation of the number of correct answers.
b) Use the mean and standard deviation to determine how many questions correct we could usually (2 standard deviations) expect from a student who randomly guesses at all 60 questions.
