Question Details

The probability distribution of all possible values of the sample proportion p is 


1. As the sample size becomes larger, the sampling distribution of the sample mean
approaches a,
(i) Binomial distribution (ii) Poisson distribution
(iii) Normal distribution (iv) chi-square distribution

2. Whenever the population has a normal probability distribution, the sampling
distribution of x is a normal probability distribution for,
(i) Only large sample sizes (ii) only small sample sizes
(iii) Any sample size (iv) only samples of size thirty or greater

3. If Z follows standard normal distribution, P(Z 1.67) is
(i) 0.5 (ii) 0.64 (iii) 0.045 (iv) 0.45

4. The probability distribution of all possible values of the sample proportion p is the
(i) Probability density function of p
(ii) Sampling distribution of x
(iii) Same as p , since it considers all possible values of the sample proportion
(iv) Sampling distribution of p
5. If X and Y are two independent ch-square variables with degrees of freedom 3 and 4
respectively, then Z=X+Y follows,
(i) Chi-square with 7 d.f. (ii) Chi-square with 12 d.f.
(iii) Chi-square with 1 d.f. (iv) None of these
