STATISTICS AND PROBABILITY

This can be used to determine the approximate value of a population parameter on the basis of a sample statistic.

What are the 3 Conceptual Approach in Probability Distribution?

• Classical, Empirical and Subjective Probability

• Classical, Binomial, and Subjective Probability

• Discrete, Relative, and Objective Probability

• Classical, Subjective, and Relative Probability

This probability is concerning about time.

• Binomial Probability

• Poisson Probability

• Hypergeometric Probability

What do "N" stands for in hypergeometric probability?

• Population size

• Sample size

• Number of successes in population

• Number of successes in sample

The z-table gives the percent of data at or below a z-score.

• True

• False

• Sometimes true, sometimes false

What is the z-value if P(z < 0.45)?

What is the z-value if P(-1.69 < z < 0.45)?

A data set has a mean of 290 and a standard deviation of 20. Calculate the z-score for an x value of 265.

What is the correct sequence for finding Probability Distribution?

• random experiment, possible outcome, sample space, random variable, realized variable, probability distribution

• sample space, random variable, random experiment, realized value, possible outcome, probability distribution

• random variable, possible outcome, random experiment, realized variable, sample space, probability distribution

A data set has a mean of 20 and a standard deviation of 3. Calculate the z-score for 23.
