Suppose in a representative sample of adult Americans ages 26 to 32 years, 28% indicated that they owned a fitness band that kept track of the number of steps walked each day and their daily activity levels. Suppose that the sample size was 300. Is there convincing evidence that more than one-quarter of all adult Americans in this age group own a fitness band? Test the relevant hypotheses using a significance level of 0.05. (a) State the appropriate null and alternative hypotheses. $H_0: p = 0.25$ versus $H_a: p < 0.25$ $H_0: p < 0.25$ versus $H_a: p > 0.25$ $H_0: p = 0.25$ versus $H_a: p \ne 0.25$ $H_0: p \ne 0.25$ versus $H_a: p = 0.25$ $H_0: p = 0.25$ versus $H_a: p > 0.25$ (b) Find the test statistic. (Round your answer to two decimal places.) $z = $ (c) Find the $P$-value. (Use the appropriate appendix table or technology. Round your answer to four decimal places.) $P$-value = (d) State the conclusion in the problem context. Fail to reject $H_0$. We have convincing evidence that more than one-quarter of all adult Americans ages 26 to 32 years own a fitness band. Fail to reject $H_0$. We do not have convincing evidence that more than one-quarter of all adult Americans ages 26 to 32 years own a fitness band. Reject $H_0$. We have convincing evidence that more than one-quarter of all adult Americans ages 26 to 32 years own a fitness band. Reject $H_0$. We do not have convincing evidence that more than one-quarter of all adult Americans ages 26 to 32 years own a fitness band.

The Dinner’s Dilemma is described as follows: ˆ n diners are going out to eat. ˆ Prior to placing their orders, they agree to split the check evenly amongst all of them. ˆ The diners have two options: Expensive Meal or Inexpensive Meal ˆ Each diner prefers – the more expensive meal to the less expensive one; – to minimize what he has to pay. – to maximize total utility (payoff from meal enjoyment minus cost of meal). Let ˆ \gamma represent the payoff from eating the expensive meal ˆ \delta represent the payoff from eating the inexpensive meal ˆ K represent the cost of the expensive meal ˆ L represent the cost of the inexpensive meal (a) Why is it reasonable to assume K − L > \gamma − \delta and \gamma − 1 nK > \delta − 1 nL (b) Let the total cost of the other players’ meals be x. What is Player i’s portion of the bill? (Your answer should depend on the type of meal Player i chooses.) (c) What is the unique pure strategy Nash equilibrium for this game? Explain your answer. (d) Explain why every player would be better off if they all ordered the inexpensive meal. (e) How is this game related to the Prisoner’s Dilemma?
