Yos, te sample size is n-20. No, the employees would not be considered independent in the present sample Moving to another question will save this response. «, s. Question 2 of 10)Explanation / Answer
Binomial distribution could only be used when all the trials in the distribution have an identical and independent distribution and the probability of success. Here due to the different experience for different employees, there are more than 2 categories. Binomial distribution is sum of n independent bernoulli trials and each bernoulli trial can only have two possible outcomes, therefore this cannot be a binomial distribution as experiences in years would have multiple outcomes.
Therefore b) is the correct answer here.
