Weschler"s intelligence scale for children (wisc iii) Huge changes in iq as much as 20pts. Diet lower in fat, sugar, and processed food correlated with an iq score up to 5 pts higher. 717 children living in urban and suburban neighborhoods. Urban significant decline in iq between 6-11. Not due to mom"s iq, education, or marital status. High levels of language and verbal skills. High level of sensitivity and emotional depth. May be vulnerable to emotional difficulties: vulnerable to classroom taunts, critical feedback, frustration with failure. May still require a school based team and an iep. As measured on intelligence assessments (below 70 iq) Abnormality on chromosome 21 trisomy (three instead of two ch21) Risk increases with age ( 1 in 1000 to 30 in 1000) Characterized by: muscular problems (low muscle tone, short stature, often develop social interaction difficulties. Involuntary urge to eat (often leads to obesity) Cardiac and kidney problems, sound sensitivity, depth perception weaknesses.

An amusement park, whose customer set is made up of two markets, adults and children, has developed demand schedules as follows:

The marginal operating cost of each unit of quantity is $5. Because marginal cost is a constant, so is average variable cost. Ignore fixed costs. The owners of the amusement part want to maximize profits.

Price ($)	Quantity
Price ($)	Adults	Children
5	15	20
6	14	18
7	13	16
8	12	14
9	11	12
10	10	10
11	9	8
12	8	6
13	7	4
14	6	2

Calculate the price, quantity, and profit if: The amusement park charges the same price in the two markets combined

Please express your answers for Price and Profit in whole dollars (i.e.10.00)

Please use whole numbers for Quanitity (i.e. 10, 27, 4)

Mick Karra is the manager of MCZ Drilling products whichproduces a variety of specialty valves for oil field equipment.Recent activity in the oil fields has cause ddemand to increasedrastically, and a decision has been made to open a newmanufacturing facility. Three locations are being considered, andthe size of the facility would not be the same in each locationThus, overtime might be necessary at times. The folowing tablegives the total monthly cost (in 1000s) for each possible locationunder each demand posibility. The probabilities for the demandlevels have been determined to be 20% for low demand, 30% formedium demand, and 50% for high demand

	Demand is Low	Demand is medium	Demand is High
Ardmore, OK	85	110	150
Sweetwater, TX	90	100	120
Lake Charles, LA	110	120	130

(a) Which location would be selected based on the optimisticcriterion?

(b) which location would be selected based on the pessimisticcriterion?

(d) which location should be selected to minimize the expectedcost of operation?

(e) How much is a perfect forecast of the demand worth?

(f) which location would minimize the expected opportunityloss?

(g) what is the expecetd value of perfect information in thissituation?
