The aim of the course is to deal with probability, laws of probability, distributions, statistical data, confidence intervals and hypothesis testing, linear correlation and linear regression. The study course is intended to acquire the mathematical knowledge and practical skills needed to study future special subjects, as well as to acquire skills for applying math techniques to study different problems related to Engineering science and related fields. During the course, students acquire skills in working with appropriate application software, such as “MS Excel”, “Matlab”.

Upon successful completion of this course:

1. Knowledge - students are able to manage and demonstrate knowledge and critical understanding of probability, laws of probability, distributions, statistical data, confidence intervals and hypothesis testing, linear correlation and linear regression. Students manage the application of the acquired topics in practical examples related to the specialty of the Engineering science and related fields – **tests**.

2. Skillis - students are able to show understanding of the corresponding concept and regularities, to perform necessary calculations and operations. Students are able to use appropriate software for calculations – **laboratory works**.

3. Competence - working in a group or doing work independently, student is able to apply the mathematical calculations corresponding to the specialty problem situation, to make a professional assessment and interpretation of the intermediate result of the calculations and the final results – **independent works**.

**Full time intramural studies:**

1. Introduction to probability (4 h)

2. Laws of probability (3 h)

3. Discrete random variables and probability distributions. (4 h)

4. Continuous random variables and probability distributions. (5 h)

5. **Test 1:** Probability. Distributions

6. Elements of mathematical statistics. Presentation of statistical data (4 h)

7. Confidence intervals for the mean and for the variance (3 h)

8. Hypothesis testing (3 h)

9. Linear regression and correlation between two variables (2 h)

10. Multiple regression and correlation (2 h)

11. **Test 2:** Elements of mathematical statistics. Confidence intervals. Hypothesis testing. Correlation and regression
**Part time extramural studies:**

All topics specified for full time studies are accomplished, but the number of contact hours is one half of the number specified in the calendar

Assessment: Exam.

In writing form and by using the appropriate software, the following independent work must be completed (all tasks are executed correctly) at times specified by the teaching staff:
**Independent work 1.** Definitions of probability. Laws of probability
**Independent work 2.** Bernoulli trials. Total probability. Bayes’ formula
**Independent work 3.** Discrete variables. Distributions
**Independent work 4.** Continuous variables. Distributions
**Independent work 5.** Mean, median, mode and standard deviation. Presentation of statistical data
**Independent work 6.** Confidence intervals
**Independent work 7.** Hypothesis testing

**Independent work 8.** Correlation and regression

The student can receive the **accumulative exam** if:

1. all independent works are completed at times specified by the teaching staff;

2. during the semester each test score is at least 4.

Failed tests can be repeated.

The student may overwrite unsuccessfully written test work during the study process, at times specified by the teaching staff. The student can rewrite the last test in the 1st week of the individual study and examination period at the time indicated by the teaching staff.

The accumulative exam mark is

- 90% of the average mark of all tests

- 10% for completed independent works.

The **written exam** can be arranged at the time indicated by the teaching staff, if all the independent works are defended (all tasks are performed correctly).
