Small, energy-efficient, Internet-centric, new computers are increasingly gaining popularity (The New York Times, July 20, 2008). Some of the biggest companies are wary of the new breed of computers because their low price could threaten PC makers' already thin profit margins. An analyst comments that the larger companies have a cause for concern since the mean price of these small computers has fallen below $350. She examines six popular brands of these small computers and records their retail prices as: (You may find it useful to reference the appropriate table: z table or t table). $322 $269 $373 $412 $299 $389 a. What assumption regarding the distribution of the price of small computers is necessary to test the analyst's claim? Assume that the price of small computers is distributed.

Cybersecurity is a critical business issue that demands the attention of business and IT executives. According to a study released by PwC, 38% of surveyed business and IT executives reported phishing scams at their institutions.Source: Data extracted from “Toward new possibilities in threat management,” PwC, 2017 pwc.to/2kwhPJv. a. If you conduct a follow-up study to estimate the population proportion of business and IT executives reporting phishing scams at their institutions, would you use a p of 0.38 or 0.50 in the sample size formula? b. Using your answer in part (a), find the sample size necessary to estimate, with 95% confidence, the population proportion to within 0.03.
The dataset below was collected from a survey to determine whether CFT development in the island can be used as a strategy for the sustainable management and utilization of the fishery and aquatic resources in small islands. It shows the monthly income (in thousand pesos) estimated by 200 randomly selected fishers in Guimaras according to the type of fishers (i.e., the income source of fishers is solely fishing or they have alternative/supplemental livelihood such as island hopping services, sari-sari store ownership, fish value adding and/or vending, souvenir selling, carpentry, as construction worker, farming and tour guiding) and their perceived benefit from CFT development in the island. From this dataset and using  = 0.05, is there a significant difference in estimated monthly income due tofisher type? How about due to the CFT perceived benefit? How about due to the interaction between fishertype and the perceived CFT benefit?a. Analyze manually and assume that the…

Of all sports, football accounts for the highest incidence of concussion in the United States due to the large number of athletes participating and the nature of the sport. While there is general agreement that concussion incidence can be reduced by making rule changes and teaching proper tackling technique, there remains debate as to whether helmet design may also reduce the incidence of concussion. Rowson et al. (2014) report on a retrospective analysis of head impact data collected between 2005 and 2010 from eight collegiate football teams. Concussion rates for players wearing two types of helmets, Riddell VSR4 and Riddell Revolution, were compared. A total of 1,281,444 head impacts were recorded, from which 64 concussions were diagnosed. The relative risk of sustaining a concussion in a Revolution helmet compared with a VSR4 helmet was 46.1%. This study illustrates that differences in the ability to reduce concussion risk exist between helmet models in football. Although helmet…
A psychologist believes that the age of an adolescent will have an impact on the number of phone calls made to the opposite sex (in heterosexual people) over the course of one month. They also suspect that gender of the adolescent will have an impact on the number of phone calls made to the opposite sex.

The 2016 Global Information Security Workforce Study(GISWS) surveyed information security professionals regarding trends and issues affecting their professions and careers. In the study, women were asked about their impact on the security posture of their organization. Twenty-eight percent of women indicated that their opinions are not valued. When comparing women who did not feel valued and women who did feel valued, the most substantial difference concerning training and leadership programs. Forty-seven percent of women that feel undervalued say their organization does not provide adequate training and leadership development resources, whereas 61% of women who do feel valued in their position indicate that their organizationdoes provide adequate training and leadership development resources.If a woman is selected at random and that woman indicates that her organization does not provide adequate training and leadership development resources, what is the probability that this woman…
Introduction Proper nutrition is critical for maximizing brain function and enhancing learning. There is accumulating evidence that early malnutrition, marked by stunting, is associated with long-term deficits in cognitive and academic performance, even when social and psychological differences are controlled. All over the world, children living without permanent parental care are at a heightened risk for under-nutrition, putting their health and development in great jeopardy. Aim To assess the nutritional and cognitive status in institutionalized orphans which might help to formulate effective interventions for improving the nutritional status of vulnerable children in future. Materials and Methods This cross-sectional, study included 70 children (35 orphans and 35 non-orphans). Their anthropometric measurements (height, weight, and BMI) were measured and cognition was assessed using subsets of Wechsler Intelligence Scale for Children-Revised (WISC-R): Block design and Digit span.…
