An operations analyst in a sheriff's department studied how frequently their emergency helicopter was used during the past year, by time of day (shift 1 2AM-8AM, shift 2 8AM-2PM, shift 3 2PM-8PM, shift 4 8PM-2AM) Random samples of size 16 for each shift were obtained. The dependent variable (freq) and the categorical variable (shift) .

Use transformation if necessary using the Box-Cox method that satisfies one way ANOVA model (State whether your transformation is valid or not). The data is attached.

Question about Java ArrayList:

how to delet congestive number:

eg : [1 2 2 3 2 2 1] -----> [1 2 3 2 1]

how to get the number that only in one list:

eg:

[2 2 1], [ 4 4 2 2], [8 8 4 4 2] -------->[1,8]

[8 8 4 4 2], [4 4 2 2], [2 2 1] --------->[1,8]

Thanks in advance

Exercise 2-40 Prepare Statements for a Manufacturing Company (LO 2-2, 4)

The following balances are from the accounts of Crabtree Machining Company:

January 1 (Beginning) December 31 (Ending)
Direct materials inventory $ 97,300 $ 109,400
Work-in-process inventory 108,400 107,200
Finished goods inventory 43,000 46,300

Direct materials purchased during the year amount to $513,200, and the cost of goods sold for the year was $1,875,000.

Required:

Prepare a cost of goods sold statement.

2. The production function is given as Q=LK1/2 with K fixed at 4 units. Note K1/2 is same as the square root of K.

a. Draw the total, average and marginal product associated with this function.

b. Write down the equations for total cost, total fixed and total variable cost when w=2 and r=3, and draw the respective diagrams.

c. Write down the equations for AFC, AVC, MC and ATC corresponding to the values of w and r as in part b, and draw the respective diagrams.

d. Using duality, answer to part a, and words, explain the shapes of AVC and MC drawn in part c.

e. If r = 4, which of the cost curves (TC, TFC, TVC, AFC, AVC, AC and MC) will change and why? (4 points)
