Identify the scores marking the 25th and 96th percentile rankings. 3. Identify the percentile rank of scores of 63 and 85. 4. From the data on page 1, construct a tabular grouped frequency, percentage, cumulative frequency, and cumulative percentage distribution with an interval width of i = 5. (Figure a top score at 99.) X (i = 5) f % fc %c 5. Identify the apparent limits for your top class interval. 6. Identify the real limits for your top class interval. 7. Identify the midpoint for your top class interval. 8. From this grouped distribution estimate the scores marking the 25th and 96th percentiles. 9. From this grouped distribution estimate the percentile rankings of scores of 63 and 85. 10. Use a histogram or a frequency polygon to depict the grouped frequency distribution. Label your graph as to whether it is a histogram or a frequency polygon.

I have paid a person and failed each question. Please look at questions indepth and ONLY respond if calculations can be performed. I am losing tooo much money here. It is not a PAPER!! This is all COMPUTATIONS. 

 

1. CBC is interested in 2 machines.  Machine A costs $120,000, lasts 5 years, and has maintenance costs of 37,000 annually for 5 years.  A has an equivalent annual cost (EAC) of 70,289.  Machine B costs $110,000, lasts 10 years and has maintenance costs of $25,000 annually for 10 years.  The cost of capital is 12%. Find the equivalent annual cost for machine B.  Which machine should be chosen?

 

2. Dale Inc. has sales of $993,489; operating expenses of $677,630; and depreciation expense of $20,000.  The tax rate is 30%.  What is the operating cash flow? Round your answer to the nearest dollar. 

 

3. You analyze a project and find that the net income of the project is $177,450 per year for the next 5 years.  The investment of $1,000,000 will be fully depreciated to a zero book value on a straight-line basis over 5 years.  The cost of capital is 12%.  Find the profitability index (PI). Do you accept the project?  Why or why not?

	A.	0.640; Yes, PI < 1
	B.	1.361; Yes, PI > 1
	C.	0.640; No, PI < 1
	D.	1.361; No, PI >
