From the time of early studies by Sir Francis Galton in the late nineteenth century linking it with mental ability, the cranial capacity of the human skull has played an important role in arguments about IQ, racial differences, and evolution, sometimes with serious consequences. (See, for example, S.J. Gould, "The Mismeasure of Man," .) Suppose that the mean cranial capacity measurement for modern, adult males is cc (cubic centimeters) and that the standard deviation is cc. Complete the following statements about the distribution of cranial capacity measurements for modern, adult males. (a) According to Chebyshev's theorem, at least ? of the measurements lie between 565 cc and 1481 cc. (b) According to Chebyshev's theorem, at least 36% of the measurements lie between and . (Round your answer to the nearest integer.) (c) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately 99.7% of the measurements lie between and . (d) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately ? of the measurements lie between 565 cc and 1481 cc.

The world post Covid 19 has created the concept of social distancing which will impact on the way we do business. Online purchasing is expected to increase because it will reduce human interaction and contribute to the reduction of Covid 19 related illnesses. However, online purchases have created contemporary legal issues which may be a novel for most legal systems in several Caribbean Countries.

You are required to

critically discuss the concept of online purchases and the various methods used in online transactions with supporting case laws. Secondly, critically discuss FIVE (5) CONTEMPORY CASE LAWS related to online purchasing at the International Level, focusing on the judgements handed down in those cases and most importantly how do you think that will impact on the Caribbean online purchaser. Finally, bearing in mind your answers above; what do you think (your opinion) that Caribbean Governments can initiate via its legal systems to enhance and protect online purchasers legal rights?

President Cyril Ramaphosa officially opened and addressed the first 4th Industrial Revolution SA - Digital Economy Summit. The Summit was hosted by the 4th Industrial Revolution South Africa partnership (4IRSA), an alliance between partners from the public and private sectors, academia and civil society. The 4IRSA partnership seeks to develop Human Resource practices that will enhance training and development in South Africa. Furthermore, the summit presented plans to develop training procedures that will be inclusive, coherent and responsive to the 4IR in the country. The president was quoted saying "Training programmes must allow learner's to be evaluated in the workplace after a period of approximately 6 months to determine whether their performance has improved and whether these improvements contributed to the achievement of objectives".

Use the statement above to identify the training level of needs the summit intended to highlight as well as the evaluation method the President suggested during the summit. Furthermore, briefly analyse the potential impact of the 4IR on the following classrooms.

 Interactive television classroom

 Distance learning

 Computer based training (20)

13. Generational Differences in Workplace Attitudes. In 2015, Addison Group (a pro-vider of professional staffing services) and Kelton (a global insights firm) surveyed the work preferences and attitudes of 1,006 working adults spread over three generations: baby boomers, Generation X, and millennials (Society for Human Resource Manage-ment website, https://www.shrm.org/resourcesandtools/hr-topics/talent-acquisition/pages /millennials-raises-promotions-generations.aspx). In one question, individuals were asked if they would leave their current job to make more money at another job. The file Millenials contains the sample data, which are also summarized in the following table.

Leave Job for More Money?
Baby Boomer

Yes 129
No 207
Generation X

yes 152
no 183
Millennial

yes 164
no 171

Conduct a test of independence to determine whether interest in leaving a current job for more money is independent of employee generation. What is the p-value? Using a .05 level of significance, what is your conclusion

Margaret is a supervisor in the online sales division of a large clothing retailer. She has let it be known that she is devoted to the firm and plans to build her career there. Margaret is hard-working and reliable, has volunteered for extra projects, has taken in-house development courses, and joined a committee dedicated to improving employee safety on the job. She undertook an assignment to research ergonomic office furniture for the head of the department and gave up several lunch hours to consult with the head of human resources about her report. Margaret filed the report late, but she explained the delay by saying that her assistant lost several pages that she had to redraft over the weekend. The report was well received, and several of Margaret’s colleagues think she should be promoted when the next opening arises.

Question: Evaluate Margaret’s skill in building a power base. What ­actions has she taken that are helpful to her in reaching her goal? Is there anything she should have done differently?

Suppose a municipality is proposing to upgrade its municipal water treatment plant to reduce pesticide contamination of its water supply to a level that does not adversely affect human health. The new plant would be constructed over the course of the initial year (year “0”) at a cost of $15 million. Once the plant begins operating in year “1”, estimated operating and maintenance costs of $3 million will be incurred per year for the life of the plant which is 12 years, and estimated accrued benefits will be $5 million per year. Conduct a benefit-cost analysis to determine whether this project should be considered feasible at a discount rate of 5%. What about a discount rate of 10%? Use Excel to save much time and effort. I have provided a template that you could use. If you prefer to do calculations manually you can complete the table below.
