A research laboratory was developing a new compound for the relief of severe cases of hay fever. In an experiment with 36 volunteers, the amounts of the two active ingredients (A & B) in the compound were varied at three levels each. Randomization was used in assigning four volunteers to each of the nine treatments. The data on hours of relief can be found in the following .csv file: Fever.csv State the Null and Alternate Hypothesis for conducting one-way ANOVA for both the variables ‘A’ and ‘B’ individually. 1.2) Perform one-way ANOVA for variable ‘A’ with respect to the variable ‘Relief’. State whether the Null Hypothesis is accepted or rejected based on the ANOVA results. 1.3) Perform one-way ANOVA for variable ‘B’ with respect to the variable ‘Relief’. State whether the Null Hypothesis is accepted or rejected based on the ANOVA results. 1.4) Analyse the effects of one variable on another with the help of an interaction plot. What is an interaction between two treatments? [hint: use the ‘pointplot’ function from the ‘seaborn’ function] 1.5) Perform a two-way ANOVA based on the different ingredients (variable ‘A’ & ‘B’) with the variable 'Relief' and state your results. 1.6) Mention the business implications of performing ANOVA for this particular case study. use python to solve this

Java Problem 3: The Snake Box Factory

Overview Dear Respectable Software Engineer,

Here at the world renowned Snake Box Factory, we pride ourselves on our ability to deliver the highest quality, custom sized, cardboard boxes to our customers. Our boxes are filled with the highest quality, custom-ordered snakes. We service thousands of accounts worldwide and have a solid 98% satisfaction rating with customers. However, the entire ordering process is currently written on cardboard, which is transported between departments via carrier snake. We thought this would be a good way to show confidence in the quality and usefulness of our product. But as our business continues to grow, we’re realizing this was a bad idea. We believe it’s time for a more conventional and digitized approach to our operations. Would you be able to help us develop the software we need to make this happen?

Sincerely,

President George Johnson, The Snake Box Factory

Tasks:

Read the scenario found in the overview and consider what objects could be modeled as part of creating a software solution. Identify 3 objects from this scenario (remember, objects can be either tangible or abstract. List 3 properties and 3 behaviors belonging to each object.

Write your solution as a document rather than a .java file.

In this assignment, you will be writing a 1,000-1,250-word essay describing the differing approaches of nursing leaders and managers to issues in practice. To complete this assignment, do the following:

Select an issue from the following list: nursing shortage and nurse turn-over, nurse staffing ratios, unit closures and restructuring, use of contract employees (i.e., registry and travel nurses), continuous quality improvement and patient satisfaction, and magnet designation.

Compare and contrast how you would expect nursing leaders and managers to approach your selected issue. Support your rationale by using the theories, principles, skills, and roles of the leader versus manager described in your readings.

Identify the approach that best fits your personal and professional philosophy of nursing and explain why the approach is suited to your personal leadership style.

Identify a possible funding source that addresses your issue. Consider looking at federal, state, and local organizations. For example: There are many grants available through the CDC, HRSA, etc.

Use at least two references other than your text and those provided in the course.

Prepare this assignment according to the APA guidelines found in the APA Style Guide, located in the Student Success Center. An abstract is not required.

This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion.

Abstract

The aim of this study was to test whether the relation between physical discipline and child aggression was moderated by ethnic-group status. A sample of 466 European American and 100 African American children from a broad range of socioeconomic levels were followed from kindergarten through 3rd grade. Mothers reported their use of physical discipline in interviews and questionnaires, and mothers, teachers, and peers rated children's externalizing problems annually. The interaction between ethnic status and discipline was significant for teacher- and peer-rated externalizing scores; physical discipline was associated with higher externalizing scores, but only among European American children. These findings provide evidence that the link between physical punishment and child aggression may be culturally specific. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
