- 6
"For binomial distribution, its principal assumptions are n independent trials with two possible outcomes (success or failure) for each trial, and the success probability remains constant for each trial. On the other hand __________ distribution doesn’t involve with independence assumption for each trial and accordingly the sampling process is established on without replacement. Because of these features, it is broadly used in various real life applications especially for acceptance sampling in quality control."
Choose the correct option to complete blank in the paragraph given above.
