Explain the structure and components of a Table with an example. Meaning of Classification and Tabulation Differences between Classification and Tabulation Structure and Components of a Table with an example Answer. Meaning of Classification and Tabulation Classification According to Secrist, “Classification is the process of arranging data into sequences and groups according to their common characteristics or separating them into different but related parts”. According to Stockton and Clark, “The process of grouping large number of individual facts and observations, on the basis of similarity among the items is called Classification”. Q2 a) Describe the characteristics of Normal probability distribution. b) In a sample of 120 workers in a factory, the mean and standard deviation of wages were Rs. 11.35 and Rs.3.03 respectively. Find the percentage of workers getting wages between Rs.9 and Rs.17 in the whole factory assuming that the wages are normally distributed. Characteristics of Normal probability distribution Formula/Computation/Solution to the problem Answer. a) Characteristics of Normal probability distribution The following are some of the characteristics of Normal distribution: 1. Normal distribution is a Continuous probability distribution 2. Its Formula/Computation/Solution to the problem Z1= (x1-µ)/σ = (9-11.35)/3.03 Q3 a) The procedure of testing hypothesis requires a researcher to adopt several steps. Describe in brief all such steps. b) Distinguish between: i. Stratified random sampling and Systematic sampling ii. Judgment sampling and Convenience sampling Hypothesis testing procedure Differences Answer. Steps for procedure of testing hypothesis Five Steps in Hypothesis Testing: 1. Specify the Null Hypothesis 2. Specify the Alternative Hypothesis 3. Set the Significance Level (a) Q4 a) What is regression analysis? How does it differ from correlation analysis? b) Calculate Karl Pearson’s coefficient of correlation between X series and Y series. x y 110 12 120 18 130 20 120 15 140 25 135 30 155 35 160 20 165 25 155 10 Meaning of Regression and Correlation Differences Formula/ Computation/ Solution to the problem Answer.

Meaning of Business forecasting Methods of Business forecasting Theories of Business forecasting Answer. Meaning of Business forecasting Business forecasting provides a guide to long-term strategic planning and helps to inform decisions about scheduling of production, personnel and distribution. These are common statistical tasks in business that are often done poorly and frequently confused with planning and setting of goals. Forecasting of USB-ED introduces participants to forecasting techniques and provides a practical understanding of the main forecasting tools used by economists, and business, marketing Q6 Construct Fisher’s Ideal Index for the given information and check whether Fisher’s formula satisfies Time Reversal and Factor Reversal Tests.

Formula of Fishers Ideal Index This method is a combination of Laspeyre’s and Paasche’s method. If we find out the geometric average of Laspeyre’s index and Paasche’s index, we get the index suggested by Fisher. Fisher’s index number is given by: Where, Get fully solved assignment 100% trusted website bcoz we use installment payment smu mba/bba/bca/mca assignment winter season (april/may exam) 2013 sem (I , II , III , IV) in only Rs 700/ sem ( 6 sub) or Rs 125/question paper.
