A study was conducted on students from a particular high school over the last 8 years. The following information was found regarding standardized tests used for college admitance. Scores on the SAT test are normally distributed with a mean of 1057 and a standard deviation of 203. Scores on the ACT test are normally distributed with a mean of 22.6 and a standard deviation of 4.9. It is assumed that the two tests measure the same aptitude, but use different scales.

If a student gets an SAT score that is the 34-percentile, find the actual SAT score.
SAT score =  
Round answer to a whole number.

What would be the equivalent ACT score for this student?
ACT score =  
Round answer to 1 decimal place.

If a student gets an SAT score of 1341, find the equivalent ACT score.
ACT score =  
Round answer to 1 decimal place.

Consider a Coffee-shop located at the School University Center, which is managed by student association, and some students work there as a manager, in the kitchen, in customer service etc. You can consider all students workers as a general term “student_employee”.

As a system designer your task is to design a UML class for a “student-employee”, try to code in C# or any OOP language, create two sample objects and show inheritances from student to the student_employee.

(a) Use an appropriate hypothesis test, at 0.01 level of significance, to determine whether there is evidence of a difference between before and after scores of the students.

(b) What assumption is necessary to perform the hypothesis test in (a)?

(c) Construct a 99% confidence interval estimate of the mean difference in before and after scores. Interpret the interval. What is your decision based on this confidence interval estimate?

(d) Compare the results in (a) and (c).

A high school kicker makes a 34.0yd field goal attempt (in American football) and hits the crossbar at a height of 12.0ft .

What is the magnitude of the net displacement of the football from the time it leaves the ground until it hits the crossbar?

What is the direction of the net displacement of the football from the time it leaves the ground until it hits the crossbar?

Assuming the football took 2.70s to hit the crossbar, what was the magnitude of its average velocity?

What was the direction of its average velocity?

Explain why you cannot determine its average speed from these data.

In a study of high-achieving high school graduates, the authors of a report surveyed 834 high school graduates who were considered "academic superstars" and 436 graduates who were considered "solid performers." One question on the survey asked the distance from their home to the college they attended.

Assuming it is reasonable to regard these two samples as random samples of academic superstars and solid performers nationwide, use the accompanying data to determine if it is reasonable to conclude that the distribution of responses over the distance from home categories is not the same for academic superstars and solid performers. Use

α = 0.05.

Distance of College from Home (in miles)
Student Group Less
than 40
40 to
99
100 to
199
200 to
399
400 or
More
Academic Superstars 158 157 143 150 226
Solid Performers 105 94 83 65 89

State the null and alternative hypotheses.

H0: Student group and distance of college from home are independent.
Ha: Student group and distance of college from home are not independent. H0: Student group and distance of college from home are not independent.
Ha: Student group and distance of college from home are independent.     H0: The proportions falling into the distance categories are not all the same for the two student groups.
Ha: The proportions falling into the distance categories are the same for the two student groups. H0: The proportions falling into the distance categories are the same for the two student groups.
Ha: The proportions falling into the distance categories are not all the same for the two student groups.


Calculate the test statistic. (Round your answer to two decimal places.)
χ2 =

What is the P-value for the test? (Round your answer to four decimal places.)
P-value =

What can you conclude?

Do not reject H0. There is not enough evidence to conclude that the proportions falling into the distance categories are not all the same for the two student groups. Reject H0. There is convincing evidence to conclude that the proportions falling into the distance categories are not all the same for the two student groups.     Reject H0. There is convincing evidence to conclude that there is an association between student group and distance of college from home. Do not reject H0. There is not enough evidence to conclude that there is an association between student group and distance of college from home.

Working in teams has become necessary in many organizations and school projects. In this class, you have also been allocated to project teams. Together with your teammates, you have accomplished two team projects. Reflect upon your experiences of the learning journey, drawing connections between Organizational Behavior theories and your team processes, and discuss accordingly. In particular:

a) What did your team do well? Identify your team’s top two key success factors and explain what interventions or unintended actions contributed to those positive experiences. (Discuss and Elaborate more with Individual Differences, Groups & Teams - 5 Stages of Team Development, Diversity & Inclusion, Leadership, Organisational Behavior, Management and other related topics.) (Word limit of 300 words)

b) What went wrong at certain points? What were the reasons behind the process losses in your team? Discuss up to two issues and explain how your team turned around these situations. (Discuss and Elaborate more with Individual Differences, Groups & Teams - 5 Stages of Team Development, Diversity & Inclusion, Leadership, Organisational Behavior, Management and other related topics.)

experiences with a school-age child whose family is at or near the poverty level. How did poverty impact their life? The chapter talks about strengths in the lives of people and families in poverty that may help them overcome the effects on a child's development and well-being. Include examples of strengths within the child and family, or relationships and resources available to them outside of the family that may have helped them overcome some of the obstacles to their success.

Assume you are employed as a counselor at your local high school. You need to conduct a 30-minute interview with a student who has suddenly had a dramatic decline in her grades. Prior to conducting any interview, it is extremely important to plan its structure, the type of information you hope to acquire, the timing and sequencing of the interview, and the types of questions you might want to ask. To prepare for the interview, analyze the structure of the interview and present a summary including the following reasons for your choices:

State the purpose of your interview and Discuss the topics you plan to cover and the sequence in which you will cover them while addressing the questions you will use to obtain the information.
