Statistics:

Statistics is a branch of mathematics dealing with data gathering, organization, analysis, understanding and performance.

It is a term used to review a process that an analyst uses to describe a data set.

If the data set depends on a sample of a larger population, then the analyst can improve explanation about the populations mainly based on the statistical outcomes from the sample.

Explanation of Solution

Courses taken in statistics:

The course of statistics are descriptive statistics and applied statistics.

Descriptive statistics

These statistics contains the methods for establishing and summarizing information.

Most part of the course is assigned with these statistics.

It also contains the creation of graphs, charts and tables and the calculation of many descriptive measures.

The descriptive measures include averages, measure of variation and percentiles...

Explanation of Solution

Experience in statistics field:

“Yes”, the user has a job experience in the field of statistics.

Depending on the area of work, the statistics employees are also known as data analysts, and data managers.

Job roles of data analysts:

The main job role of data analysts is to interpret data, analyze the results using statistical techniques and offer ongoing reports.

Data analyst will develop and execute the data collection systems.

The strategies of data analyst optimize statistical efficiency and data quality...

6. See the code below and solve the following. import java.io.*; public class DataStream { } public static void main(String[] args) } DataOutputStream output = new DataOutputStream(new FileOutputStream("temp.dat")); output.writeUTF("Book1"); output.writeInt(85); output.writeUTF("Book2"); output.writeInt(125); output.writeUTF("Book3"); output.writeInt(70); output.close(); // ToDo: Read all data from temp.dat and print the data to the standard output (monitor) 6-1. This program has a compile error, and the message is “Unhandled exception type FileNotFoundException". How do you fix this error? (1 point) 6-2. Is FileNotFoundException a checked exception or an unchecked exception? (1 point) 6-3. What is the difference between checked exception and unchecked exception? (1 point) 6-4. Please complete the above program by reading all data from temp.dat and print the data to the standard output (monitor) by using System.out.print, System.out.println or System.out.printf method. (2 points)

Write a program that reads a list of integers from input and determines if the list is a palindrome (values are identical from first to last and last to first). The input begins with an integer indicating the length of the list that follows. Assume the list will contain a maximum of 20 integers. Output "yes" if the list is a palindrome and "no" otherwise. The output ends with a newline. Hints: - use a for loop to populate the array based on the specified size (the first number entered) - use a for loop to check first value with last value, second value with second from end, etc. - if the values do not match, set a Boolean variable to flag which statement to output (yes or no) Ex: If the input is (remember to include spaces between the numbers): 6 1 5 9 9 5 1 the output is: yes Ex: If the input is: 5 1 2 3 4 5 the output is: C++ coding
