A true-false question is to be posed to a husband & wife team on a quiz show. Both the husband and the wife will independently give the correct answer with probability 0.6. Compute the probability of a correct answer for each of the following strategies.

a) Let the wife answer the question always.

b) Have them both consider the question, and then either give the common answer if they agree or, if they disagree, flip a fair coin to determine which answer to give.

A student is taking a multiple-choice quiz in which each question has five possible answers, exactly one of which is correct. He knows 85% of the material being tested. Assume the teacher has chosen the questions independently and at random from among all the questions she could have chosen. When the student knows the correct answer to a given question, he has a 98% chance of marking it correctly. When he does not know the answer, he answers by marking...

Agree or Disagree and Why? Question: Are decision makers risk takers or risk avoiders? Answer: Decision makers are put in different situations that will give them the opportunity to be both. They would be a risk taker if the probability of the situations will be in their favor. Whether the situation allows profit or potential loss, it is always important to manage the risk. Risk avoiders would try to eliminate the exposure to losses at any cost. Some might see...

(b) The mean of a population is the same as that of a sample. (c) If a value appears more than half in a sample, then the mode is equal to the value. 2.
