1. Discuss the purposes of (1) substantive tests of transactions, (2) tests of controls, and (3) tests of details of balances. Give an example of each.

2. Discuss the four business functions that result in sales transactions in a typical sales and collection cycle and, for each function, state the key documents and records involved.

1
Demonstrate the use of local variables in a Java program that has
1 function

2
Demonstrate the use of overloaded methods
each has three primitive parameters
two methods computes and returns the product to the calling method for printing
one method computes and prints the product; does not return a result

3
Demonstrate the use of overloaded constructors
Three constructors each initialize two variables
Three methods, 1 computes the radius of a circle, 1 computes the area of a rectangle, and area of sphere

Set T of integers is recursively defined as follows:

1. 1 is in set T

2. If x is in set T, then x + 2 and 2 ∙ x are both in T.

Which of these integers are in set T? 0 7 11 13 19 24

please explain why if possible, thank you!

1. 1. In polarizing microscopy, what is and what happens when a sample is anisotropic?

2. 2.What can happen to image of an anisotropic sample when you rotate it?

3.      3.What additional piece of equipment is added to a polarizing microscope to control anisotropic behavior? How does it accomplish control?

This question requires using Rstudio. This is following commands to install and import data into R:

> install.packages("ISLR")
> library(ISLR)
> data(Wage)

The required data installed and imported, now this is description of the data:

This dataset contains economic and demographic data for 3000 individuals living in the mid-Atlantic region. For each of the
3000 individuals, the following 11 variables are recorded:

year: Year that wage information was recorded
age: Age of worker
maritl: A factor with levels 1. Never Married 2. Married 3. Widowed 4. Divorced and 5.
Separated indicating marital status
race: A factor with levels 1. White 2. Black 3. Asian and 4. Other indicating race
education: A factor with levels 1. < HS Grad 2. HS Grad 3. Some College 4. College Grad
and 5. Advanced Degree indicating education level
region: Region of the country (mid-atlantic only)
jobclass: A factor with levels 1. Industrial and 2. Information indicating type of job
health: A factor with levels 1. <=Good and 2. >=Very Good indicating health level of worker
health ins: A factor with levels 1. Yes and 2. No indicating whether worker has health insurance
logwage: Log of workers wage
wage: Workers raw wage

This question continues with the Wage dataset.
(a) Create a binary variable, wage150, that contains a 1 if wage contains a value above
150, and a 0 if wage contains a value below 150.
(b) Fit a logistic regression model on the training data with the response variable being
wage150 and predictor variables being year, age, and education.

Please provide all necessary codes using Rstudio.

1. Suggest a viable technique for purification of the crude SNAR product and outline the procedure for this technique and rationalize our choice. (SnAr mechanism)

22.3 Procedure

A solution of 4-chlorobenzyl amine (2.0 mmol, 1 mL 2.0 M soln. in 2-propanol, 2 equiv.) is added to a stirred solution of methyl 4-fluoro-3-nitrobenzoate (1.0 mmol) in 2-propanol (~10 mL) in a 25 mL round bottom flask equipped with a reflux condenser. The reaction mixture is heated to reflux for 30 min, cooled in an ice-water bath, and the product isolated by vacuum filtration. The crude product is rinsed with ice-cold 2-propanol (2 × ~3 mL), air-dried, and characterized via NMR (CDCl3) and IR spectroscopic analysis

What is the waiting time and Turnaround time of each process for each of the scheduling algorithms? [12 Marks]

(b) Preemptive PRIORITY scheduling [2 Marks]

(c) Highest Response Ratio Next (HRRN) scheduling

(d) Round Robin (RR) (quantum = 4) scheduling

(e) Which of the foregoing scheduling policies provides the lowest waiting time for this set of jobs? What is the waiting time with this policy? (Show your work)

Following is information on two alternative investments being considered by Jolee Company. The company requires a 6% return from its investments. (PV of $1, FV of $1, PVA of $1 and FVA of $1). (Use appropriate factor(s) from the tables provided.)
  

a. For each alternative project compute the net present value.

A basketball coach wanted to see if there was a relationship between a team and their training methods. 50 players were asked "Do you think practicing 5 times per week will help you win more games?" Below are each teams responses.  

Null hypothesis: A team and their training methods are independent.

Alternative hypothesis: A team and their training methods are dependent.  

Perform hypothesis testing using the Chi-Square Test for Independence and interpret the results.
