Statistics  – Important Question Bank  for JKBOSE (Summer Zone & Winter Zone) HSC Examination 2016

We had mentioned some tips for cracking the HSC JKBOSE Jammu and Kashmir exam here: HSC Study Tips to Crack HSC Exams.

We had also shared Important Questions Bank for HSC Examination 2016 and students have really appreciated it and showered us with love last year.

Today, we are posting the Statistics – Important Questions Bank for Jammu and Kashmir JKBOSE HSC 2016 Examination to make life easy for all you HSC students.

Without making you wait any further, please find the questions below:

Long Question Mark 5: , find the probability that:

2. Define Poisson distribution and give thee instance where Poisson distribution can be employed. Obtain Mean and Variance of the Poisson distribution.

3. Explain the layout of Latin Square Design. Discuss the applications, advantages and disadvantages of Latin Square Design.

4. What are the basic principles of Design of Experiment? Discuss them in detail.

5. Using Fisher’s ideal formula, compute price and quantity index numbers for 1984 with 1982 as base year for the following data:

 Commodity {A} Commodity {B} Commodity {C} Year Price [Rs] Quantity [Kg.] Price [Rs] Quantity [Kg.] Price [Rs] Quantity [Kg.] 1982 5 10 8 6 6 3 1984 4 12 7 7 5 4

6.  Define the terms: Price relatives, Quantity relatives and Value relatives and show how they are related to each other?

7. Tabulate the given data for standardized death-rate by Direct and Indirect methods:

 Standard Population Population A Age in Years Population in 000’s Sp-Death – rate Population in 000’s Sp-Death rate [0-5] 08 50 12 48 [5-15] 10 15 13 14 [15-50] 27 10 15 09 [50 to Above] 05 60 10 59

8. What is meant by Fertility of Population? Explain any three measure of Fertility.

9.  Consider the given equations as the lines of regression i.e. 4 x – 5 y + 30 = Zero and 20 x – 9 y = 107, which of these is the line of regression of ‘x’ on ‘y’? Also find r xy and σ x, when σ y = 3.

10. Prove compute regression coefficients form the information given N = 10, Σy = 210, Σ(x – 35)2 = 162. Σ(y – 31)2 = 222 and Σ(x – 35) (y – 31) = 92.

Short Question Mark 3:

11. Given mean of binomial distributing equal to 2 and the variance equal to 4/3. Calculate the probability of getting.

• Exactly two successes
• Less than two successes.

12.  If the variance of Position’s distribution is 2. Find the distribution for x = 1,2 and 3. Give e-2 = 0.1358.

13.  Calculate the minimum number of replications so that an observed difference of 10% of the mean will be taken as significant at 5% level. The C.I. of plot values being 12%.

14. Give the merits of weighted average of relative indices.

15.  What do you understand by the terms specific death rate and specific birth rate. Give the formula of these rates for computation.

16.  What do you understand by the terms specific death rate and specific birth rate. Give the formula of these rates for computation.

17.  Give the use of Vital statistics in day to day experiences.

18.  Compute  and r(x, y) form the regression equations, given:

8 x – 10 y + 66 = 0

40 x – 18 y = 214.

Very short Question Mark 2:

19.  Define a Bernoulli variate and hence define Bernoulli distribution.

20. Briefly give the utility of Consumer price indices.

21. What do you understand by the term Measurement of population?

22. Give that: regression coefficient b xy = 9/20, regression coefficient b xy = 4/5. Compute correlation coefficient r(x, y).
