(using R)The iris data set in R gives the measurements in centimeters of the variables sepal length and width andpetal length and width, respectively, for 50 flowers from each of 3 species of iris, setosa, versicolor, andvirginica. Use the iris data set and the t.test function, test if the mean of pepal length of iris flowers isgreater than the mean of sepal length.The iris data set in R gives the measurements in centimeters of the variables sepal length and width andpetal length and width, respectively, for 50 flowers from each of 3 species of iris, setosa, versicolor, andvirginica.

Write a Java Program to manage student information of a university. The Javaprogram does the following steps:a) The program must use single-dimensional arrays to store the studentinformation such as Student ID, Name and Major.b) The program asks the user to provide the number of students.c) The program asks the user to enter the Student IDs for the number of studentsand stores them.d) The program asks the user to enter the corresponding names for the numberof students and stores them.e) The program then asks the user to provide the corresponding major for thestudents and stores them.f) The program then should display the following options:1. ID Search2. Major Enrollment3. Exitg) On selecting option 1, the user can search for a student using Student ID. Theprogram asks the user to enter a Student ID. It then should print thecorresponding student’s details such as Name and Major if the user providedStudent ID number is present in the stored data. If the user’s Student IDnumber does not…

- (a) Algebraically determine the output state |q3q2q1q0> (which is a 4-qubitvector in 16-dimensional Hilbert space). Show all steps of your calculations. (b) Run a Qiskit code which implements the circuit and append threemeasurement gates to measure the (partial) output state |q2q1q0> (which is a 3-qubit vector in 8-dimensional Hilbert space). this is for quantum soft dev class, you can use stuff like Deutsch Jozsa if u wantarrow_forwardWrite a C++ program that will count from 1 to 10 by 1. The default output should be 1, 2, 3, 4, 5, 6 , 7, 8, 9, 10 There should be only a newline after the last number. Each number except the last should be followed by a comma and a space. To make your program more functional, you should parse command line arguments and change behavior based on their values. Argument Parameter Action -f, --first yes, an integer Change place you start counting -l, --last yes, an integer Change place you end counting -s, --skip optional, an integer, 1 if not specified Change the amount you add to the counter each iteration -h, --help none Print a help message including these instructions. -j, --joke none Tell a number based joke. So, if your program is called counter counter -f 10 --last 4 --skip 2 should produce 10, 8, 6, 4 Please use the last supplied argument. If your code is called counter, counter -f 4 -f 5 -f 6 should count from 6. You should count from first to last inclusively.…arrow_forwardWrite a program that will count from 1 to 10 by 1.

- A Dia file has been created for you to extend and can be found on Company.dia represents a completed ER schema which, models some of the information implemented in the system, as a starting point for this exercise. Understanding the ER schema for the Company database. To demonstrate that you understand the information represented by the schema, explain using EMPLOYEE, DEPARTMENT, PROJECT and DEPENDENT as examples: attributes, entities and relationships cardinality & participation constraints on relationships You should explain questions a and b using the schema you have been given to more easily explain your answers. Creating and Extending Entity Relationship (EER) Diagrams. To demonstrate you can create entity relationship diagrams extend the ER as described in Company.dia by modelling new requirements as follows: Create subclasses to extend Employee. The employee type may be distinguished further based on the job type (SECRETARY, ENGINEER, MANAGER, and TECHNICIAN) and based…arrow_forwardComputer programs can be very complex, containing thousands (or millions) of lines of code and performing millions of operations per second. Given this, how can we possibly know that a particular computer program's results are correct? Do some research on this topic then think carefully about your response. Also, explain how YOU would approach testing a large problem. Your answer must be thoughtful and give some insight into why you believe your steps would be helpful when testing a large program.arrow_forwardCould you fix this?
