Re: Gauhati University 2nd year B.Com Quantitative Methods in Business sample Paper
Here you are looking for sample Paper of 2nd year B.Com Quantitative Methods in Business of Gauhati University, as you want here I am providing you. Gauhati University was founded in 1948 under the Guwahati University Act 1947.. Facilities at Gauhati University - Library Classrooms Guest House Canteen Sports and Recreation Bank Computer Center Faculties at Gauhati University - Faculty of Arts Faculty of Science Faculty of Commerce Faculty of Management Faculty of Law Faculty of Medicine Faculty of Fine Arts Faculty of Engineering Faculty of Technology Gauhati University 2nd year B.Com Quantitative Methods in Business sample Paper Full Marks: 80 Time: three hours 1. ans the subsequent questions: (a) Fill in the blank: Sampling errors are not current in ___________________. (b) select the accurate answer: If the correlation ranging from 2 variables X and Y is negative, then the regression coefficient of X on Y is i) Positive ii) Negative iii) either positive or negative iv) zero (c) What is the range of Karl Pearson's correlation coefficient? 1 (d) choose the accurate option out of the provided ones: 2 Index number is a i) measure of relative modifications ii) special kind of avg. iii) percentage relative iv) All the above (e) Mention 2 control charts for variables. 1 {f} elaborate the parameters of binomial distribution? 1 (g) describe feasible region associated with the solution of LP issues by graphical method. 1 (h) State whether the subsequent statement is actual or False: 1 "Linear programming deals with issues involving only a single objective.” 2. ans any 5 of the subsequent questions: 5×5=25 a) Enumerate the different steps in sample survey. b) State the multiplicative legal regulations of probability and illustrate it with an example. c) If 5% of electric bulbs manufactured by a company are defective, use Poisson distribution to obtain the probability that in a sample of 100 bulbs (i) none is defective, (ii) five bulbs are defective. (Given e-5 = 0 . 007) d) elaborate the characteristics of normal distribution? e) explain in brief the issues of inventory management. f) Write a note on Pareto's legal regulations of income distribution. g) 2 persons X and Y were asked to rank seven various kinds of perfumes. The ranks provided by them are as follows: Perfumes: A B C D E F G X: two one four three five seven 6 Y: one three 3 four five six 7 find rank correlation coefficient. 3. (a) A issue in Statistics is provided to 5 students A, B, C, D and E. Their probabilities of solving it are ½, , ¼, ¼ and 1/5 respectively. What is the probability that at lowest 1 learner will be able to solve the problem? 7 (b) The distribution of monthly incomes of 500 workers is presumed to be normal with mean of Rs 2,000 and standard deviation of Rs 200. Estimate the number of workers with incomesi) exceeding Rs 2,300 p.m.; ii) ranging from Rs 1,800 and Rs 2,300 p.m. What is the least income of the 25% workers in the highest income group? [Given: Z = 0.67 1.00 1.50 Area = 0.25 0.3413 0.4322] 3+3+2=8 4. (a) find Karl Pearson's correlation coefficient for the subsequent bivariate distribution: 7 x : one two three four five six seven eight 9 y : nine eight 10 12 11 13 14 16 15 (b) discuss the concept of regression. elaborate regression equations and regression lines? Why there are usually 2 regression lines? When do they coincide? 3+2+2+ one =8 5. (a) elaborate type- I fault and type-II fault associated with tests of significance? discuss the concept of level of significance. 5+2=7 (b) 2 sample poles of votes for 2 candidates A and B for a public office are taken, one from among the residents of urban areas and the other from the residents of rural areas. The outcomes are provided beneath. Use chi-square test to examine whether the nature of the area is related to voting preference in this election: Votes For A B Total Rural 620 380 1000 Urban 550 450 1000 Total 1170 830 2000 Given: X 2 0.05 (1) = 3.84 8 6. (a) A company requires 10000 units of raw materials per annum. The cost per order is estimated to be Rs 50. The storage cost is estimated to be Rs.5,00 per unit of avg. inventory. What volume should be ordered so that the total cost is minimum? obtain also the total minimum cost excluding the purchase cost. 5+3=8 (b) What is a control chart? discuss the background of 3cr control limits for a control chart. 4+3=7 7. (a) explain the advantages and disadvantages of OR models. 7 (b) Solve the subsequent LPP by graphical method: 8 Maximize Z = 40x + 80y subject to 2x+3y 48 x 15 y 10 x, y 0 8. (a) Solve by simplex method : 10 Maximize Z = 3x1+ 2x2 + 5X3 subject to x1+2x2 +x3 430 3x1 + 2x3 460 x1+4x2 420 x1,x2,x3 0 (b) Write a note on the role and limitations of simulation. 5 Foe more details contact to this address: Address: Gauhati University National Highway 37, Gopinath Bordoloi Nagar, Jalukbari Guwahati, Assam 781014 Map; [MAP]https://www.google.co.in/maps/place/Gauhati+University/@26.153684,91.6625485,16z/data=!4m2!3m1!1s0x0:0x95386a0503457611 [/MAP] |
