(a) Exactly two workers suffer from the disease.
(b) Not more than 2 workers suffer from the disease.
4. Explain the meaning of sampling distribution of a sample statistic. Obtain the sampling distribution of mean in case of sampling from infinite populations.
5. A company wants to study the relation between R and D expenditure (X) and sales (Y) for the
ten-year period. Determine the correlation  coefficient between these variables.

(e) Mixed Auto-regressive - moving average models
 
SECTION - B
7. The mean life of a sample of 10 electric bulbs was found to be 1456 hours with a standard deviation of 423 hours. A second sample of 17 bulbs chosen from a different batch showed a mean life of 1280 hours with a standard deviation of 398 hours. Is there a significant difference between the means of the two batches ?
8. What is skewness ? Distinguish between Karl Pearson's and Bowley's coefficient of skewness.

MS-8 : QUANTITATIVE ANALYSIS FOR MANAGERIAL APPLICATIONS

SECTION - A
1. The cost accountant of a company has derived the following expression relating total cost C to
the number of units (x) of a product.
C=1440 +125x + 0.1x2
Find :
(a) The number of units (x) that will minimise the average cost.
(b) The value of average cost and total cost corresponding to above number of units.

2. The residents of
Lucknow city were surveyed recently to determine readership of newspapers
available. 55% of the residents read the morning paper, 65% read the evening paper, and 30% read both newspapers. Find the probability that a resident selected reads either the morning or
evening paper or both the papers.
3. In a factory, four workers are assigned to complete an order received for dispatching 2000 boxes of a particular commodity. Worker A takes 10 minutes per box, B takes 15 minutes per box,
C takes 20 minutes per box and D takes 25 minutes per box. Find the average time taken
per box by the group of workers.
4. An auto company decided to introduce a new six cylinder car whose mean petrol consumption is claimed to be lower than that of the existing auto engine. It was found that mean petrol
consumption for the 100 cars was
15 km per litre with the standard deviation of 5 km per litre.
Test for the company at 5% level of significance whether the claim that the new car petrol
consumption is
14.50 km per litre on the average is acceptable. The critical value of Z at 5% level
of significance is 1.96.
5. Define Hypothesis. Explain various types of errors in testing of Hypothesis. Describe various steps involved in the "Hypothesis Testing".

6. Write short notes on any three of the following : 3x5

(a) Polynomial Function

(b) Median

(c) Criterion of pessimism

(d) Cluster sampling

(e) Delphi method of forecasting
SECTION - B
7. Using the method of least squares, find the regression equation of x on y for the data given in the table below :
x 1 2 3 4 y 6 9 12 15 18 And from the regression equation obtained, find the value of x corresponding to y = 20.
8. Solve the following system of non-homogeneous linear equations using Cramer's rule : x + 2y — z = —1 3x + 8y + 2z = 28 4x + 9y + z =14

SECTION - A
1. A maruti car is purchased for Rs. 60,000/-. If the depreciation for the first three years is at 15% per annum and for the next two years is at 20% per annum, then calculate the depreciated value of the car at the end of five years.

2. It has been observed that on an average one telephone number out of ten is busy. Using binomial distribution find the probability that if five randomly selected telephone numbers are called
(a) not more than two will be busy
(b) at least four of them are busy

 

3. A builder employs three types of workers : male, female and children. He pays Rs. 350, Rs. 250 and Rs. 200 per day to a male, female and child worker respectively. Suppose he employs 40 males, 30 females and 10 children, determine

(a) Average wage per day paid by the builder

(b) Average wage per day paid by the builder if the number of males, females and children employed are equal.
