A teacher needs list to fill student scores on five assignments.There are 15 students in her class.The students are numbered 1 through 15.Use nested for loops to print out the list for the teacher.

Sally, a used-car broker needs to transport her inventory of cars from Irvine and Santa Ana to used-car auctions being held in Anaheim and Huntington Beach. Sally currently uses a trucking company that charges her for each car shipped. The transportation costs from each origin city and destination city are:

Origin	Destination	Cost per Car Shipped	Capacity (# Cars)
Irvine	Costa Mesa	$8	10
Irvine	Santa Ana	$5	10
Santa Ana	Costa Mesa	$9	10
Santa Ana	Huntington Beach	$20	20
Costa Mesa	Anaheim	$6	No limit
Costa Mesa	Huntington Beach	$7	No limit
Huntington Beach	Anaheim	$6	10

Sally has 15 cars in Irvine and 15 cars in Santa Ana. She wants to ship 20 cars to Anaheim and 10 cars to Huntington Beach in the cheapest way possible. She knows that it might make sense to ship some cars through Costa Mesa; there is a parking lot there where cars can be transferred from one truck to the next.

Formulate this problem as a linear program (algebraically define all decision variables, all constraints and the objective function). Do not solve it.

Question 2

Like other higher education institutions, York University is intensely preparing for the start of the new academic year in September, when a large new cohort of students will enter York for their first year of higher education. For the purpose of this question, we will assume that this preparation includes a contingency plan to deal with the a situation where limits will still be in place on in-person gatherings during the start of the fall 2020 term. Considering our course content on socialization and organizational culture, describe your own socialization process to York. Use your own socialization experiences when you came to York U as examples when you apply relevant concepts. Then, identify challenges and opportunities for the socialization process of newly admitted students that are expected to start their studies at York in September 2020. Explain why it is important for organizations such as York U to get the socialization process right in September. Ensure to articulate your arguments clearly and provide support for your claims, using and applying relevant concepts.

Which study design is best to minimize confounders--cohort or case-control?

Part A - Palindromic Bitlists Write a function palindrome binary(n) which returns a list of bitlists of length n, where every bitlist is a palindrome. The returned list of bitlists must be in lexicographical order (think about the order of your options). You must use backtracking to solve this problem (i.e. do not use brute force).

Part B - All Paths Write a function all paths(M, u, v) which takes as input an adjacency matrix of a graph, M, and two vertices u, v and returns a list of all paths from u to v in M. A path is a list of vertices. Note that a path cannot use the same vertex twice, but two different paths can use some of the same vertices. The returned list of paths must be in lexicographical order. You must use backtracking to solve this problem (i.e. do not use brute force).

PYTHON CODE

Cohort Study Design

Suppose that you have been hired by the UF student health services department to design a cohort study to assess the following hypothesis among UF students: Irregular sleep patterns increase the risk of headaches.

Be sure that your design addresses the following elements:

1. Refine the study hypothesis so that it is as specific as possible and contains all elements of a “good” hypothesis.
2. How will you identify and define the cases?
   • Are there any exclusion criteria that you would apply?
3. How will you sample from the underlying population for your “controls”?
   • Who will you select as controls?
   • How will you select them?

4. How will you define the exposure of interest?
   • How will you collect the information on exposure?
5. What other information do you want to know about participants that may be related to the exposure of interest and/or the outcome (potential confounders)? Of these, what will you be able to collect and what will you be unable to collect?
6. Which measures of disease frequency and association will you calculate?
7. What are the strengths and limitations of your study?
   • Which limitations could be removed by using a different study design?
8. What other information would you like to know to design this study?
9. there is no such data, this is just hypothetical study case that what we can do in this case? also there is another question on chegg but not answer in detail like HOW and WHAT

Your task is to calculate the average height of students in the class. You will gather each of the student’s height and put it in a list. then you will throw out the shortest and tallest height to take care of any statistical anomalies. Then you will add the heights and divide by the number of student’s in the class.

Heights of Students in inches

Max=77
Josefine=67
Hannah=66
Mia=65
Ben=74
Kevin=70
Marie=64
Aidan=70

Steps On Python:

Declare a list to contain the heights in inches

Ask the user to input values

Add each value to the list

Use appropriate list function to find smallest object

Use appropriate list function to remove that smallest object

Use appropriate list function to find largest object

Use appropriate list function to remove that largest object

Use appropriate list function to add objects in the list,

Then Use appropriate list function to divide that amount by the number of objects in the list

Then print the objects and the average height of students in the class.

Using the 3 program files below to read the sample students.txt file and create a singly linked-list of students. The code in sll_list.h and mainDriver.c shouldn't be changed, only sll_list.c. The finished program should print out a list that initializes the sampled 5 students and allows the user to use the functions found in mainDriver.c.
