1. In a pulse rate research, a simple random sample of 120 men results in a mean of 80 beats per minute, and a standard deviation of 11 beats per minute. Based on the sample results, the researcher concludes that the pul ...
Suppose that utility payoffs depend on decisions and states as shown in Table 1.3. Letp(θ1,),p(θ2)) denote the decision-makers subjective probability distribution over Ω = {θ1 ,θ2}. a. Suppose first that B = 35. For what ...
Let (N, Y, (F i ) i ∈N , s, P) be an Aumann model of incomplete information with beliefs, and let W ⊆ Y be an event. Prove that (N,W, (F i ∩ W) i ∈N , P(· | W)) is also an Aumann model of incomplete information with be ...

Suppose that a certain college class contains 65 students. Of these, 35 are seniors, 33 are biology majors, and 5 are neither. A student is selected at random from the class. (a) What is the probability that the studen ...
Part -1: 1) The final project is like a VERY abbreviated mini research report, where you will be running a combination of descriptive statistics and inferential statistics on a dependent variable and an independent varia ...
A ski gondola carries skiers to the top of a mountain. It bears a plaque stating that the maximum capacity is 14 people or 2324 lb. That capacity will be exceeded if 14 people have weights with a mean greater than 2324 l ...
