4. NFL Combine

The 40-yard dash time (i.e. the amount of time it takes to run 40 yards of the prospective NFL running backs is normally distributed with a mean of 4.53 seconds and a standard deviation of 0.2 seconds. For the corner backs, it is also normally distributed with a mean of 4.46 seconds and a standard deviation of 0.3 seconds.

(a) Find the probability that a running back finishes the 40 yard dash between 4.33 and 4.73 seconds.

(b) Find the probability that a randomly selected running back outruns a randomly selected corner back (i.e. the probability that the running back completes a 40 yard dash more quickly than a corner back).

(c) Find the probability that a random sample of n=25 corner backs will have an average dash time of less than 4.40 seconds.

(d) Suppose that a single line backer (not a corner back and not a running back- so you don't know the population mean or variance) ran 41 40 yard dashes, over the course of one week. His average time over these 41 trials was 4.50 seconds and the standard deviation was 0.3 seconds. Find a 95% confidence interval for the mean of his true 40 yard dash time.

FINANCIAL LEVERAGE EFFECTS - Hello! This is all one question, thank you very much in advance! Will thumbs up for answer! :D

The Neal Company wants to estimate next year's return on equity (ROE) under different financial leverage ratios. Neal's total capital is $13 million, it currently uses only common equity, it has no future plans to use preferred stock in its capital structure, and its federal-plus-state tax rate is 40%. The CFO has estimated next year's EBIT for three possible states of the world: $4.1 million with a 0.2 probability, $2.9 million with a 0.5 probability, and $0.3 million with a 0.3 probability. Calculate Neal's expected ROE, standard deviation, and coefficient of variation for each of the following debt-to-capital ratios. Do not round intermediate calculations. Round your answers to two decimal places at the end of the calculations.

Debt/Capital ratio is 0.

Debt/Capital ratio is 10%, interest rate is 9%.

Debt/Capital ratio is 50%, interest rate is 11%.

Debt/Capital ratio is 60%, interest rate is 14%.

Tombro Industries is in the process of automating one of its plants and developing a flexible manufacturing system. The company is finding it necessary to make many changes in operating procedures. Progress has been slow, particularly in trying to develop new performance measures for the factory.

In an effort to evaluate performance and determine where improvements can be made, management has gathered the following data relating to activities over the last four months:

The president has read in industry journals that throughput time, MCE, and delivery cycle time are important measures of performance, but no one is sure how they are computed. You have been asked to assist the company, and you have gathered the following data relating to these measures:

Required:

1-a. Compute the throughput time for each month. (Round your answers to 1 decimal place.)

1-b. Compute the manufacturing cycle efficiency (MCE) for each month. (Round your answers to 1 decimal place.)

1-c. Compute the delivery cycle time for each month. (Round your answers to 1 decimal place.)

3-a. Refer to the inspection time, process time, and so forth, given for month 4. Assume that in month 5 the inspection time, process time, and so forth, are the same as for month 4, except that the company is able to completely eliminate the queue time during production using Lean Production. Compute the new throughput time and MCE. (Round your answers to 1 decimal place.)

3-b. Refer to the move time, process time, and so forth, given for month 4. Assume that in month 6 the inspection time, process time, and so forth, are the same as in month 4, except that the company is able to eliminate both the queue time during production and the inspection time using Lean Production. Compute the new throughput time and MCE.. (Round your answers to 1 decimal place.)

This is all one question:

A theater uses the following table/sheet to manage ticket sales, which turned out to be a very bad practice. The manager of theater hires you to design a database to manage the ticket sale information.   

TICKET-SALES (InvoiceNumber, CustomerID, ShowTitle, SeatType, SeatLocation, TicketPrice, CustomerName, CustomerCell, ShowTime, Director_of_Show)

Note: A customer can purchase multiple seats in one order (with one InvoiceNumber). It is also the common sense that the price of a ticket/seat depends on the show, it’s showtime and seat location. Also note this theater may have multiple shows at the same time.  

To do your job, you need to answer the following questions:  

-List al Functional Dependencies

-List Multivalued Dependencies, if there is any.

-What is the key of original table (TICKET-SALES)?

-What normal form this table is in and Why? Give a clear justification/explanation

-How do you normalize it? Show the result of normalization

Please show work/explain on each question:

Ahmadi, Inc. has been manufacturing small automobiles that have averaged 50 miles per gallon of gasoline in highway driving. The company has developed a more efficient engine for its small cars and now advertises that its new small cars average more than 50 miles per gallon in highway driving. An independent testing service road-tested 64 of the new small automobiles. The sample showed an average of 51.5 miles per gallon. The population standard deviation is 4 miles per gallon.

Ahmadi, Inc wants to conduct a hypothesis test to determine whether or not it is legitimate campaign that the new small cars average more than 50 miles per gallon in highway driving. Use α = 0.05
