Identifying Binomial Distributions. In Exercises, determine whether the given procedure results in a binomial distribution (or a distribution that can be treated as binomial). For those that are not binomial, identify at hast one requirement that is not satisfied
Smartphone Survey In a Ring Central survey, 380 different smartphone users are randomly selected without replacement. Respondents were asked to identify the only thing that they can’t live without. Responses consist of whether a smartphone was identified.
To be a binomial probability distribution, a procedure must satisfy the following four requirements:
1. Here, 380 (fixed number of trials) different smartphone users are randomly selected without replacement.
2. Here, we assume that the population is very large and the sample size is less than 5% of the population. So, from the 5% Guideline for Cumbersome Calculations, if a sample size is no more than 5% of the size...
