1. An oil company conducts a geological study that indicates that an exploratory oil well should have a 20% chance of striking oil. The company is interested to find the probaiblity that the first strike comes on the third well drilled. Which distribution distribution will be used?

2. When can we use a normal distribution to approximate a binomial distribution?

3. The parameters of hypergeometric distributions are

Note that $N$ is population size, $n$ is sample size, $p$ is the probability of successes, $K$ is number of successes stated in the populaiton, $k$ is the number of observed successes.

4. In normal distribution, the proportion of observations that lies between 1 standard deviations of the mean is closest to

5. The mean deviation of a normal distribution is

6. The formula of mean of uniform or rectangular distribution is as

7. Which of the distribution have larger variance than it s mean

12. For Beta distribution of 2nd kind, the range of $X$ is

13. Themean of the Poisson distribution is 9 then its standard deviation is

14. An oil company conducts a geological study that indicates that an exploratory oil well should have a 0.25 probability of striking oil. The company is interested to find the probability that the 3rd strik comes on the 6th well drilled. Which distribution will be used?

15. If $X$ follows Goemtric distribution with parameter $p$ (probability of success) then the Mean of $X$ is

16. In binomial probability distribution, the formula of calculating standard deviation is

17. The Chi-Square distribution is a special case of

18. If $N$ is population size, $n$ is the sample size, $p$ is probability of success, $K$ is number of successes stated in population, $k$ is the number of observed successes, then the parameters of binomial distribution are

19. For beta distribution of 1st kind, the range of $X$ is

20. The normal distribution is also classified as

Probability distributions are the foundation for various statistical tests like hypothesis testing. By comparing observed data to a theoretical distribution (the null hypothesis), we can assess the likelihood that the data arose by chance.

Probability distributions are crucial tools in data analysis. They help identify patterns, outliers, and relationships between variables. Furthermore, many statistical models depend on specific probability distributions to function accurately.
