"Variables" and "Samples" are mentioned quite regularly in the process of data-gathering. Why are they so important to a researcher and what significance do they play in reporting, distorting, or manipulating outcomes... THEN... Review one of the TEDTalks videos (Located in the Modules)...3 paragraphs...which did you watch...why did you choose it? Second, summarize what your heard/saw. Three, why is this important to the understanding of social issues and society at large in regards to outcome data and application of science to understand the social world?

Write a program that prompts the user to enter the number of
students and each student’s name and score, and finally displays
the student with the highest score and the student with the
second-highest score. Use the next() method in the Scanner class to
read a name rather using the nextLine() method.

A trapezoid is a quadrilateral in which two opposite sides are parallel. (note: all squares, rectangles, and parallelograms are trapezoids)
Note 1: the length of Base 1 is always greater than or equal to Base 2
Note 2: To form a valid trapezoid, if must satisfy the side/length rule, namely, the sum of the lengths of Leg1,Leg2 , and Base 2 must be greater than the length of Base 1
Note 3:If a default trapezoid is created, set all the sides equal to 1 (i.e., a square, or rhombus)
The following is the UMs for a trapezoid:
Trapezoid |
-base1 : double -base2: double -leg1: double -leg2: double |
+Trapezoid() +Trapezoid (base1, base2, leg1, leg2) // setters and getters +print(void): void +toString(void) : string |
For the driver program:
Note 1: If the user creates a trapezoid that violates the side/length rule (including 0 or negative side lengths), throw an exception
Note 2: If the user sets one of the sides that violates the side/length rule, do not change the side, and throw an exception
A main drvier (main8a.cpp) :
#include <iostream> #include "trapezoid.h" using namespace std; int main() { cout << "Welcome to Lecture 16: Exceptions and Templates" << endl; cout << "The Trapezoid Program!\n"; cout << "\nTry creating t1 (no parameters, which is valid):\n"; try { Trapezoid t1; // this is valid, by design t1.print(); } catch(string errorMsg) { cout << errorMsg << endl; } cout << "\nTry creating t2(15,3,3,3) (which is invalid):\n"; try { Trapezoid t2(15,3,3,3); // this is invalid t2.print(); } catch(string errorMsg) { cout << errorMsg << endl; } cout << "\nTry creating t3(5,3,4,4) (which is valid):\n"; try { Trapezoid t3(5,3,4,4); // this is valid t3.print(); } catch(string errorMsg) { cout << errorMsg << endl; } cout << "\nTry changing base1 of default t4 to 10 (which is invalid):\n"; try { Trapezoid t4; t4.setBase1(10); // this is invalid t4.print(); } catch(string errorMsg) { cout << errorMsg << endl; } cout << "\nTry changing leg2 of t5(55,30,15,12) to 6 (which is invalid):\n"; try { Trapezoid t5(55,30,15,12); t5.setLeg2(6); // this is invalid t5.print(); } catch(string errorMsg) { cout << errorMsg << endl; } cout << "\nTry changing leg1 of default t6 to .5 (which is valid):\n"; try { Trapezoid t6; t6.setLeg1(.5); // this is valid t6.print(); } catch(string errorMsg) { cout << errorMsg << endl; } return EXIT_SUCCESS; }

The air in a building is to be maintained at 25°C dry bulb temperature and 60% relative humidity when the outside conditions are 35°C, 50% saturation with a barometric pressure of 101.3 kPa. The total heat gains to the room are 15 kW sensible heat and 3 kW latent heat. There is no recirculation and the fresh air passes over a cooling coil to dehumidify it, and then a heater before entering the room. The cooling coil by pass factor is 0.18; the volume flow of fresh air is 5m3/s. Calculate (a) the temperature of the air leaving the cooling coil; (b) the refrigeration load for the coil in kW; (c) the heat supplied in the heater in kW.

Using C language:
void show_array (int data[ ], int n);
void InsertionSort (int data[ ], int n);
void SelectionSort (int data[ ], int n);
where data[] is the array and n is the size of the array.
If you implement both sort routines you will need to make a copy of the original unsorted array before using the first sort, or else the second sort will be working on a sorted version of the array.

first three normalization processes. (1NF, 2NF & 3NF)
• The minimum number of records in the table must be 10
• Make sure you carry the same table from 1NF to 2NF and 3NF, do
not use separate tables from scratch for all the three forms.
• Brief explanation of the normalization processes must be

For this problem, carry at least four digits after the decimal
in your calculations. Answers may vary slightly due to
rounding.
In a random sample of 70 professional actors, it was found that 42
were extroverts.
(a)
Let p represent the proportion of all actors who are
extroverts. Find a point estimate for p. (Round your
answer to four decimal places.)

(b)
Find a 95% confidence interval for p. (Round your
answers to two decimal places.)
lower limit 2
upper limit 3
Give a brief interpretation of the meaning of the confidence
interval you have found.
We are 95% confident that the true proportion of actors who are extroverts falls outside this interval. We are 5% confident that the true proportion of actors who are extroverts falls within this interval. We are 5% confident that the true proportion of actors who are extroverts falls above this interval. We are 95% confident that the true proportion of actors who are extroverts falls within this interval.

Do you think the conditions n·p > 5 and n·q > 5 are satisfied in this problem? Explain why this would be an important consideration.
Yes, the conditions are satisfied. This is important because it allows us to say that p̂ is approximately binomial. No, the conditions are not satisfied. This is important because it allows us to say that p̂ is approximately binomial. No, the conditions are not satisfied. This is important because it allows us to say that p̂ is approximately normal. Yes, the conditions are satisfied. This is important because it allows us to say that p̂ is approximately normal.
