- Q1Which statement is true about a continuous random variable?It only takes non-negative values greater than zero.It can only take integer values.It is characterized by a fixed number of trials.It can take an infinite number of possible values in a given range.30s
- Q2Which distribution is typically used to model the number of successes in a fixed number of trials with the same probability of success?Normal distributionPoisson distributionBinomial distributionUniform distribution30s
- Q3What kind of distribution is used to model the number of events happening in a fixed interval of time or space?Binomial distributionPoisson distributionNormal distributionExponential distribution30s
- Q4Which distribution would you use to model the probability of a certain number of defects in a batch of products where the average number of defects per batch is known?Uniform distributionPoisson distributionBinomial distributionContinuous distribution30s
- Q5If a random variable represents the amount of time someone spends waiting for a bus and can take any value within a specified range, what type of random variable is it?Poisson random variableBernoulli random variableContinuous random variableDiscrete random variable30s
- Q6If you flip a fair coin 10 times, which distribution can be used to model the probability of getting a specific number of heads?Poisson distributionExponential distributionNormal distributionBinomial distribution30s
- Q7What is the main difference between a binomial distribution and a Poisson distribution?A binomial distribution can only take continuous values, whereas a Poisson distribution is always discrete.A binomial distribution requires events to happen continuously over time, while a Poisson does not.A binomial distribution always describes rare events, while a Poisson distribution is only for common events.A binomial distribution has a fixed number of trials, while a Poisson distribution counts events in a fixed interval with no upper limit on number.30s
- Q8You are monitoring a call center, and you want to model the number of calls received in an hour. Which distribution should you use?Geometric distributionBinomial distributionNormal distributionPoisson distribution30s
- Q9Which type of distribution would you use to model the probability of a student making a certain number of errors on a multiple-choice test where each question has only one correct answer?Uniform distributionPoisson distributionExponential distributionBinomial distribution30s
- Q10If a random variable describes the heights of students in a class, what type of random variable is it?Binomial random variableContinuous random variableDiscrete random variablePoisson random variable30s
