(1 point) The following Exercise is based on summary statistics rather than raw data. This information is typically all that is presentedin published reports. You can calculate inference procedures by hand from the summaries. Use the conservative Option 2 (degrees offreedom the smaller of n – 1 and n2 – 1 for two-sample t confidence intervals and P-values. You must trust that the authorsunderstood the conditions for inference and verified that they apply. This isn’t always true.)Equip male and female students with a small device that secretly records sound for a random 30 seconds during each 12.5-minuteperiod over two days. Count the words each subject speaks during each recording period, and from this, estimate how many wordsper day each subject speaks. The published report includes a table summarizing six such studies. Here are two of the six:Sample Size Estimated Average Number(SD) of Words Spoken per DayStudy Women Men WomenMen16464 15671 (7579) 16995 (9034)22524 16758 (7781) 12093 (8397)Readers are expected to understand this to mean, for example, the 64 women in the first study had x = 15671 and s = 7579.It is commonly thought that women talk more than men. Does either of the two samples support this idea? For each study:(a) State the alternative hypothesis in terms of the population mean number of words spoken per day for men (UM) and for women(HF).

Complete 12 page APA formatted essay: Management Systems & Financial Information for Decision Making.

Additionally, key information regarding revenue and company’s overall performance help them in their regular decision making (Tesco, 2014a. BT, 2014a).

Managers and executives operate at middle level and operational level within a corporation. They are essentially responsible for a variety of operational, strategic and investment related decision making on a regular basis. However, all these decisions require accurate, consistent, timely and reliable financial information regarding firm’s activities. For instance, managers at Tesco are responsible for sales forecasting and projections and for this purpose they need information such as past revenue data, sales volume and so on. Another illustration can be, if an operational manager wishes to minimise operational cost at BT, then the manager will require information related to various general and operational expenses. Such information can be obtained only from the financial statements of BT (Tesco, 2014a. BT, 2014a).

Owners and partners are ultimately held responsible for proper functioning of a business firm. Organisations such as BT and Tesco are public corporations that are managed by group of shareholders where primary decision making is done by board of directors and chairman of the company. Board of directors including the chairman are responsible for framing strategic decision such as merger and acquisition, expansion to new market, new product development and undertaking new projects.
