Do education programs for preschool childrent that follow the Montessori method perform better than other programs? A study compared 5-year-old children in Milwaukee, Wisconsin, who had been enrolled in preschool programds from the age of 3.

A. Explain why comparing children whose parents chose a Montessori school with children of other parent would not show whether Montssori schools perform better than other programs. (In fact, all the children in the study applied to the Montessori school. The school district assigned students to Montessori or other preschools by a random lottery.)

B. In all, 54 children were assigned to the Montessori school and 112 to other schools at age 3. When the children were 5 parents of 30 of the Montessori children and 25 others could be located. Those parents who were located agreed to and subsequently participate in testing. This information reveals a possible source of bias in comparison to the outcomes. Explain why?

C. One of the many response variables was score on a test of ability to apply basic mathematics to solve problems. Here are summaries for the children who took this test:

Group: n x s

Montessori 30 19 3.11

Control 25 17 4.19

Is there evidence of a difference in the population mean scores? (The researchers used two-sided alternative hypotheses.)

Paraphrase the following. please try not to make it short. needs urgently.. thanks in advance. i just want to avoid plagiarism.

Significant research has been completed regarding the importance of effective preparation of principals as school leaders and fundamental changes in the school environment.

1. Curriculum Design - Principals are faced with the critical task of assigning teachers in different grades which includes special need teachers as well to teach curriculum that is comprehensive and more encompassing. While assigning grades principle has to check whether he /she is assigning the experienced or the best teachers for each grade.
2. Parental Involvement - One of the biggest frustrations faced by principals is that parental involvement is lacking to support the institution’s effort towards improving student achievement. It has both positive and negative impacts for having parents’ involvement in the school. For instance, the negative impact could be interfering the decisions taken by the principles.

3. Communication & Collaboration - Principals and staff spend so much energy on building relationships with students, teachers, and staff. This relationship could be fruitful if the school has review programs twice in a term where teachers could freely convey their concerns to the principle. Therefore, it’s good to have communication between the teachers and the principle. This will lead to have a collaborative working environment for the subordinators.
4. Decision-making - Principals’ decisions and strategies are critically important to institutional performance. They are accountable for high levels of student achievement. Teachers and parents have to listen and follow the decisions taken by the principle.

Question 1:

Read the following situations and decide if the situation described is a symptom or a problem. If it is a symptom, provide an example of what the underlying problem might be. If it is a problem, provide an example of what symptom we might see.

Alcatel, a flip-phone manufacturer, discovers its phone's features are viewed as inadequate by target consumers.
Abercrombie & Fitch discovers its sales are falling short of its goals.
Time Warner Cable discovers its customer satisfaction scores declined for the third year in a row.
PacSun discovers its advertisements during Golden Girls reruns are not reaching its target market.

i need a thesis statement for gender inequality that is arguable, and has three supporting arguments

it can be about wage gap, women sexual harrasment, patriachy

this was mine but i wasnt sure if its arguable and is good

Discriminatory challenges for women start in childhood as young girls may believe that they are only suitable for certain professionals or in some cases, only for women and mothers. These consistent messages might lead to a false belief that women are not part of the corporate environment. Gender lines were drawn early, and women's exclusion persisted during adulthood. In this paper I will argue that women are discriminated in society. I will illustrate this by explaining women's sexual abuse on a daily basis, the hierarchical roles in which they engage in and the wage gaps, and women's experience in authority are seen as less important.

IN PYTHON

INF 120 – Project #6.5

In project 6.5 we are going to create a program and test cases to test each path/branch through the program.

Our program is going to get a word from the user and check if it is a palindrome. If it is it will output to the user that it is a palindrome. A palindrome is where the word is the same forwards as backwards.

For example racecar.If the word isn’t a palindrome then we will “translate” the word to pig Latin according to the following rules.1. If the word begins with a consonant move the 1st letter to the end of the word and then append “ay”. So dog becomes ogday.2. If the words begins with a vowel just add “ay” to the end of the word. So elk becomes Elkay.

Write your program and get it working.

Answer the following questions about your program.

1. How many paths/branches are in your program.

2. For each path/branch in your program craft a test case.

3. Run your program with each test case and screenshot the result and include them as the answer to this question.

What is BI and how can it be used to attain a competitive advantage? Use the mini-case "The Metropolitan Medical Group," found in chapter 10 of the textbook, as the basis for your response. Please cite your resources to support your position.

MINI CASE::The Metropolitan Medical Group (MMG) merged with the Oak Grove Medical Group(OGMG). The Oak Grove Medical Group has four offices and owns the medical office build-ing where their imaging and radiology lab and physical therapy and diagnostic laboratory cen-ters are located.Although the size of staffs in both practices is about the same, OGMG has a very different fi-nancial structure. Not only are their receivables a lot higher, but the aging of their receivables ismuch older. This has caused them to miss payments to their vendors, resulting in a higher ac-counts payable balance. Further analysis revealed that some of the doctors from remote officeshave referred patients for laboratory tests and to specialists outside the practice when these sametests or specialists are available internally at other offices.The room that houses the network servers is not climate controlled, secure, or backed upoff-site
