- A restaurant frequently offers a special prix fixe meal and has been charging $160 per person for the event. At that price, they’ve been averaging 30 customers each time. Their marketing firm has convinced them that they’ll gain a customer for every dollar they lower the cost of the event, and conversely lose a customer for every dollar they raise the cost. Their fixed cost per event is $2600 and preparing each customer’s meal costs an additional $40.

In League B, the pitcher must bat. The common belief is that this results in League A teams scoring more runs. In interleague play, when League A teams visit League B teams, the League A pitcher must bat. So, if the DH does result in more runs, it would be expected that league A teams will score more runs in League A park than when visiting League B parks. To test this claim, a random sample of runs scored by league A teams with and without their DH is given in the accompanying table. Complete parts c) through d) below.arrow_forward
- A course has 30 students and four possible letter grades A, B, C, D. What is the maximum number of students who are guaranteed to obtain the same gradearrow_forwardA Gallup survey showed that in March 2011 , 8 of every 25 employers in the United States were adding more workers to their workforce, 9 of 50 were reducing their workforce, and 1 of 2 were keeping it the same. In a metropolitan area there are 1250 employers and of those who will hire, they will hire an average of seven new employees. If the employers who were cutting their workforce in that area were planning on letting go an average of nine workers, what would the net change in jobs for the area be? This metropolitan area would see a ▼net decrease or increase of jobs.arrow_forwardA consumer is given the chance to buy a baseball card for $1, but hedeclines the trade. If the consumer is now given the baseball card, willhe be willing to sell it for $1? Standard consumer theory suggests yes, butbehavioral economists have found that “ownership” tends to increase thevalue of goods to consumers. That is, the consumer may hold out for someamount more than $1 (for example, $1.20) when selling the card, eventhough he was willing to pay only some amount less than $1 (for example,$0.88) when buying it. Behavioral economists call this phenomenon the“endowment effect.” John List investigated the endowment effect in a randomized experiment involving sports memorabilia traders at a sports-card show. Traders were randomly given one of two sports collectibles, say good A or good B, that had approximately equal market value.1 Those receiving good A were then given the option of trading good A for good B with the experimenter; those receiving good B were given the option of…arrow_forward
