4 1/0/0 4

Prerequisites: Foundation course (No prerequisites).

Course Objectives: To learn

• random variables that describe randomness or an uncertainty in certain realistic situation
• binomial geometric and normal distributions
• sampling distribution of mean, variance, point estimation and interval estimation
• the testing of hypothesis and ANOVA
• the topics those deals with methods to find roots of an equation
• to fit a desired curve by the method of least squares for the given data
• solving ordinary differential equations using numerical techniques

Course Outcomes: After learning the contents of this course the student must be able to

• differentiate among random variables involved in the probability models which are useful for all branches of engineering
• calculate mean, proportions and variances of sampling distributions and to make important decisions s for few samples which are taken from a large data
• solve the tests of ANOVA for classified data
• find the root of a given equation and solution of a system of equations
• fit a curve for a given data
• find the numerical solutions for a given first order initial value problem
