A chocolate chip cookie manufacturing company recorded the number of chocolate chips in a sample of 70 cookies. The mean is 22.24 and the standard deviation is 2.44. .Construct a 98​% confidence interval estimate of the standard deviation of the numbers of chocolate chips in all such cookies. How do I find the degree of freedom, which is 69, using the chi critical value table? 69 is not listed on there, just 60 and 70. Not sure how to use my TI-84 calculator to figure it out.

Write a JavaFx program for addition of two numbers. (create text as Number1, Number2 and Result and create 3 textfileds. Create sum button. You have to enter number1 and number2 in the textfileds. If you click the button Sum, the result will be showed in the third text field.

write a java code to implement a linked list, called CupList, to hold a list of Cups.

1.Define and write a Cup node class, called CupNode, to hold the following information about a cup:

•number (cup number)

•capacity (cup capacity in ml)

•Write a method size() that returns the number of elements in the linkedlist CupList.

•Write a method getNodeAt() that returns the reference to cup node object at a specific position given as a parameter of the method.

•Write a method, insertPos(),  to insert a new CupNode object at a specific position given as a parameter of the method.

•Write a method, deletePos(),  to remove the CupNode object at a specific position given as a parameter of the method.

•Write a method, swapNodes,  to swap two nodes at two positions pos1 and pos2 given as parameters of the method.

Implement the Cup list using double linked list.

•Update CupNode class by adding a link to the previous node in the list. Then update the constructor of the class

•Update the CupList by adding a last attribute, to hold the reference to the last node of the list.

•Implement the following methods in CupList isEmpty(), size(), insertAtFront(), insertAtRear(), insertAt(), removeFirst(), removeLast(), removeAt().

  CupNode should have a constructor and methods to manage the above information as well as the link to next node in the list.

2.Define and write the CupList class to hold objects of the class CupNode. This class should define:

a)a constructor,

b)a method isEmpty() to check if the list is empty or not,

c)a method insert() that will allow to insert a new cup node at the end of the list,

d)a method print() that will allow to print the content of the list,

e)A method getCupCapacity() that will return the capacity of a cup given its number. The method should first find out if a cup with that number is in the list.

3.Write a TestCupList class to test the class CupList. This class should have a main method in which you perform the following actions :

a)Create a CupList object,

b)Insert five to six CupNode objects into the created Cup List,

c)Print the content of your cup list,

d)Search for a given cup number in the list and print out its capacity.

An article in Computers & Electrical Engineering, “Parallel simulation of cellular neural networks” (1996, Vol. 22, pp. 61–84) considered the speed-up of cellular neural networks (CNN) for a parallel general-purpose computing architecture based on six transputers in different areas. The data follow: 3.775302 3.350679 4.217981 4.030324 4.639692 4.139665 4.395575 4.824257 4.268119 4.584193 4.930027 4.315973 4.600101 Round your answers to 3 decimal places. Assume population is approximately normally distributed. (b) Construct a 99% two-sided confidence interval on the mean speed-up. Enter your answer; confidence interval, lower bound ≤μ≤ Enter your answer; confidence interval, upper bound (c) Construct a 99% lower confidence bound on the mean speed-up. Enter your answer in accordance to the item c) of the question statement ≤μ

Nine principles of successful nursing leadership

Principle #4: Create and develop leaders

An old adage is, “If your unit or department can run without you, you have done your job.” This is true, so develop your succession plan early. You can’t doo it all alone. Identify your informal and formal leaders and invest in them. Take them to meetings with you; have them provide presentations to the staff and senior-level leaders. Find opportunities to highlight their strengths and minimize their weaknesses. Train them to be the next leaders.

I need to write a response to why this would be a good leadership style for a discussion board

At what levels are unemployment liabilities incurred? What are some additional employer-borne liabilities that exist with having employees?

Todd’s Direct, a major TV sales chain headquar-tered in New Orleans, is about to open its first outlet in Mobile, Alabama, and wants to select a site that will place the new out-let in the center of Mobile’s population base. Todd examines the seven census tracts in Mobile, plots the coordinates of the center of each from a map, and looks up the population base in each to use as a weighting. The information gathered appears in the following table. CENSUS TRACT POPULATION IN CENSUS TRACT X, Y MAP COORDINATES 1. 101 2,000(25, 45) 2. 102 5,000 (25, 25) 3. 103 10,000 (55, 45) 4. 104 7,000 (50, 20) 5. 105 10,000 (80, 50) 6. 106 20,000 (70, 20) 7. 107 14,000 (90, 25) a) At what center-of-gravity coordinates should the new store be located? b) Census tracts 103 and 105 are each projected to grow by 20% in the next year. How will this influence the new store’s coordinates

Write a Python program to simulate a very simple game of 21
•Greet the user.
•Deal the user a card and display the card with an appropriate message.
•Deal the user another card and display the card
.•Ask the user if they would like a third card. If so, deal them another card and display the value with an appropriate message.
•Generate a random number between 10 and 21 representing the dealer’s hand. Display this value with an appropriate message.
•If the user’s total is greater than the dealer’s hand and the user’s total is NOT greater than 21, the user wins, otherwise the dealer wins. Display the player’s and the dealer’s totals along with an appropriate message indicating who won.

Pharmacists have, in the past, had a marketing problem. While this has improved over time, they still have a long path ahead of them until they are effectively spreading the message about their skills and abilities to everyone who needs to know.

Reflect on your work over the past year. Identify a service that pharmacists are qualified to provide (ex: diabetes education). This truly can be anything within their scope of practice. (Recall: Under a collaborative practice agreement, their scope of practice is whatever the collaborating provider allows).

When you have identified this service, consider who needs to know that you are providing this service and how you will let them know. Answer the following questions regarding the service :

1) Explain the current situation from the point of view of all relevant stakeholders (patients, prescribers, pharmacy staff, etc.) What would you like the situation to look like for all the stakeholders when the service is fully implemented?

2) What strengths do you have that you would be able to use in implementing this service?

3) What are your weaknesses that will limit your ability to implement this service?

4) What are the major budget considerations for implementing this service? Specifically, a) what makes this profitable? b) what are the necessary inputs and resources needed to provide the service?  

5) Who is your target audience?

6) What do you intend to do to gain attention, interest, desire, and action to implement the campaign?
