2. ANOVA was introduced by:

R.A Fisher

3. The test statistic used in analysis of variance procedure follow the ....... distribution.

F

4. For testing of hypothesis about population proportion, we use:

5. Sample proportion is an/are ___ estimator of population mean.

Unbiased

6. A statistic whose standard error decreases
7. We can apply method of Maximum Likelihood on:

Discrete as well as continuous variables

8. β is the probability of:

Accept H0/H0 is false

9. Accept H0/H0 is false, is the ________. Type II error
10. Conventionally, the probability of making a type-II error is denoted by:

Beta

11. ________ are equivalent:

Type-I error and level of significance.

12. In general, the estimators obtained by the method of moments are ______. Inefficient
13. The larger the n, the smaller the standard error, and so the narrower the:
14. If we have the following information: p=0.16, q=0.84, z=1.96 and e=0.05, then sample size will be:

207 n = z2.p.q/ e2

15. “A point estimate plus/minus a few times the standard error of that estimate”. This statement represents:
16. The maximum likelihood estimators (MLE) are ____ and ____ but not necessarily____. Consistent, efficient, unbiased
17. Inferential statistics involves

All of above

18. Method of moments for estimation of parameters is based on the theory of

Nonlinear estimation

19. If Var (mean1) < Var (mean2) it implies Mean 1 is more efficient
20. An estimator is said to be efficient if it has Smallest variance

21 In binomial distribution the sample size is considered to the sufficiently large, if both np and nq are greater than or equal to:
