In Java 

Create a Student grading system.

You should use a person base class (stores the name of the student).

Derive a student class from the person class. The student class stores the student ID.

The student class should also store the students 3 exams (Test 1, Test 2, and Test 3) and calculate a final grade (assume the 3 tests count equally).

Create an array of students for a class size of 15 students.  

You can use the keyboard to read in all of the data for the 15 students (name, ID, and 3 grades), or read this data from a text file (PrintWriter).

If using a text file, you can use Comma Seperated values (see Case study in Chapter 10 page 748 for examples how to do this), below also shows how you can read CSV (see below).

 String line = "4039,50,0.99,SODA"

 String[] ary = line.split(",");

 System.out.println(ary[0]); // Outputs 4039

 System.out.println(ary[1]); // Outputs 50

 System.out.println(ary[2]); // Outputs 0.99

 System.out.println(ary[3]); // Outputs SODA

Once all the data is Imported, you can average all the exams and create a final letter grade for all students.

A - 90-100

B - 80-89

C - 70-79

D - 64-69

F < 64

The program should create an output showing all the data for each student as well as writing all the results to a file (using PrintWrite class).

Hand in all data (program, output file, and a screenshot of the output of the program).

(1 point) 1. In a study of red/green color blindness, 850 men and 2450 women are randomly selected and tested. Among the men, 72 have red/green color blindness. Among the women, 5 have red/green color blindness. Test the claim that men have a higher rate of red/green color blindness.

The test statistic is

The p-value is

 Is there sufficient evidence to support the claim that men have a higher rate of red/green color blindness than women using the 0.01% significance level?

A. Yes

B. No

2. Construct the 99% confidence interval for the difference between the color blindness rates of men and women.

Which of the following is the correct interpretation for your answer in part 2?

A. We can be 99% confident that the difference between the rates of red/green color blindness men and women lies in the interval

B. There is a 99% chance that the difference between the rates of red/green color blindness men and women lies in the interval

C. We can be 99% confident that the difference between the rates of red/green color blindness men and women in the sample lies in the interval

D. None of the above.

Personnel at an airport control tower track a UFO. At 11:02 a.m. it is located at a horizontal distance of 2.00 km in the direction 30⁰ N of E at an altitude of 1200 m. At 11:15 a.m. the location is 1.00 km at 45⁰ of E at an altitude of 800 m. What was the displacement of the UFO? Express your result in component notations.

Consider the reversible, elementary, gas phase reaction shown below that
occurs at 300 K in a constant volume reactor of 1.0 L.
k]
A + B ( ) C, k1 = 6.0Lmol-1 h-1,k2 = 3.0h-1
k2
For an initial charge to the reactor of 1.0 mol of A, 2.0 mol of B, and no C,
find the equilibrium conversion of A and the final pressure of the system. Plot
the composition in the reactor as a function of time.

A crate of mass 45.0 kg is being transported on the flatbed of apickup truck. The coefficient of static friction between the
crate and the truck's flatbed is 0.360, and the coefficient ofkinetic friction is 0.230.
(a) The truck accelerates forward on level ground. What is themaximum acceleration the truck can have so that
the crate does not slide relative to the truck's flatbed?
(b) The truck barely exceeds this acceleration and then moves withconstant acceleration, with the crate sliding
along its bed. What is the acceleration of the crate relative tothe ground?

A 200 kg wood crate sits in the back of a truck. The coefficient of static friction between the crate and the truck is s = 0.5, and the coefficient of kinetic friction is k = 0.3. The truck starts off up a 15° slope.
(a)  What is the maximum acceleration the truck can have that will not cause the crate to slip out the back?
(b)  What is the maximum acceleration the truck can have that will not cause the crate to slip out the back if the truck is going down the hill?
