Periodically, Merrill Lynch customers are asked to evaluateMerrill Lynch financial consultants and services (2000 MerrillLynch Client Satisfaction Survey). Higher ratings on the clientsatisfaction survey indicate better services, with 7 the maximumservice rating. Independent samples of service ratings for twofinancial consultants are summarized here. Consultant A has 10years of experience, whereas consultant B has 1 year experience.Use α = 0.05 and test to see whether the consultant with moreexperience has the higher population mean service rating. ConsultantA Consultant B n1=16 n2 =10 x1 =6.82 (with bar overx) x2 = 6.25(with bar over x) s1 =0.7 s2 = 0.8 a.) State the null and alternative hypothesis. b.) compute the value of the test statistic.

In 2000 Nokia wanted to enable knowledge management and learning alternatives across its whole value chain - Suppliers (Busines-2-Business B2B), Customers (Business-2-Customers B2C) and Employees (Business-2-Employees B2E). This perspective would allow Nokia to deliver understanding how to over 200 million people. Enabling suppliers, customers, and employees easy, collaborative and timely access to essential and valuable information about Nokia's products and services, would increase production, commercial awareness and improved dedication from its value string through upgraded services, products, tools and information. Knowledge Management System in Nokia is divided into 3 levels: Individual level, Group level and Organizational level. Knowledge Architecture in Nokia practices Nonaka's model. You can find four ways to capture Knowledge: tacit to tacit communication (socialization), tacit to explicit communication (externalization), explicit to tacit communication (internalization), explicit to explicit communication (combination).
One of the primary Knowledge Management enabler is Nokia Research Centre (NRC), which is implemented for exploring new frontiers for freedom, solving scientific issues to convert the converging Internet and marketing communications establishments. Another enabler, Customer Relationship Management (CRM), Nokia uses CRM to extend the usage of vital customer information to the mobile workforce, ensuring they have got the required resources, when and where they want them. Also Supply Chain Management (SCM) is a KM enabler, Nokia has integrated an operating model by using SCM to accomplish one with their central strategies, which is to add new-product speedily that reflect consumers' fast-changing mobile phone tastes to ensure an industry advantage which emphasize rapid-response processing, quick-ship logistics, and a "global resource web" that links back to you Nokia's crops and suppliers. There are many companies became Kilometers enablers for Nokia to achieve their Kilometers goals. They may be Liquid Air Laboratory GmbH, Psiloc, Kuneri Ltd. , Citrix Systems, Inc. , DiVitas Systems, Mobien Systems Private Limited, Oracle Corp., Sam Click Ltd., iGuanaMobile Sdn Bhd, SYSOPENDIGIA plc, Openbit Ltd. , Secure Digital Box AG.
In spite of the scientific possibilities and an increased volume of computer engineers and information systems professionals, Nokia continue steadily to face serious knowledge management problems, due to the insufficient interdisciplinary knowledge required for an integrated method of the complex information activities involved with every part of work and doing business. As Nokia runs globally, they cannot fully understand the information trends and the implications of the global information societies and information fads. To overcome this issue Nokia is spending abundant money on expensive technology and tools that are not exploited to the higher benefit of the organization. Nokia, regardless of the socioeconomic and politics systems in which they operate, need large numbers of information. That is especially true for those in transitional economies. Hence Nokia is suffering from inefficient and inadequate supervision and exploitation of these information resources.

AEROSPACE ENGINEERING PROBLEM

Calculate the propellant mass required to launch a 2000 kg spacecraft from
180 km circular earth orbit on a Hohmann transfer trajectory to the orbit of Saturn.
Calculate the time required for the mission, and assume the propulsion system has a
specific impulse of 300 seconds. Saturn's orbit about the Sun is 1.43x10⁹ km and
the Earth's orbit about the Sun is 149.6x10⁶ km.

Could someone please give me a hand. Thank You :)

1. Suppose your average number of work hours per year has been 2000 hours with a standard deviation of 118 hours. Please graph and calculate the probability you will work between 1900 hours and 2300 hours next year. Hint: Two Zs and be ready to add. Use the “old” Z formula for this problem.

2. Based on the information in Problem #1, please calculate the probability you will work between 2300 and 2500 hours next year. (again please use the “old” Z formula”

A 100-lb driver and a 2000-lb tractor lift 900 lb of gravel. Create a MATLAB program that will:  

Determine the reaction at each of the two rear wheels and two front wheels.

The shift has changed and a new driver dumped some of the gravel. Ask the user the weight of the new driver and the weight of the gravel left in the tractor.  

Calculate the new reaction at each of the two rear wheels and two front wheels.  

Provide the user with output that describes the difference between a and c.  

An avid fan of early 2000's baseball wanted to test whether corked bats actually improved a baseball bat's hitting power to see if Mark McGuire was wrongfully removed from Backyard Baseball 2003. To do so, the researcher gathered 25 men together from his college campus and divided into two groups, Group A with 13 people and Group B with 12. Group A was given batting practice with corked bats whereas Group B used standard wood bats. Group A hit an average of 11.4 balls into the outfield with s = 2.2. Group B averaged hitting 9.7 balls into the outfield with s = 3.5. Assume the two groups are independent.

Rounding to three units, the lower bound, for a 95% confidence interval for ?μ_{1 -} ?μ₂ using conservative degrees of freedom would be:

Rounding to three units, the upper bound, for a 95% confidence interval for ?μ₁ - ?μ₂ using conservative degrees of freedom would be:

Suppose that: S&P 500 index is trading at 2000; index stocks do not pay any dividends; and you can borrow and lend at 5% per annum. You have an index portfolio worth $20 million. An index futures contract with a multiplier of 100 matures in a year – this means one futures contract represents an index basket of stocks with a market value of 100 times the index value. How will you fully hedge your portfolio for a one year horizon? What’s your return if futures are trading at 2100? 2150? 2050? Suppose, you want to hedge only for one month. Do you know what your return will be if index futures are trading at 2100? 2150? 2050? Suppose your portfolio is only $300,000. Can you hedge perfectly? Suppose your portfolio is different from the index basket of stocks – what is the quality of your hedge?

If you could reinvest the cash flow stream of $1000, $1200, $1500, $1700, $2000, $2500, $2900, and $3500 at 11.5% interest, how much will you have from this investment in 8 years? (In other words, what is the future value of this stream of cash flows?) Note that the cash flows are not necessarily the same as the previous problem's cash flows. Round to the nearest cent.
