Question

assignment 1 replacement: problem 4 (1 point) for each problem, select the best response. (a) a phenomenon is observed many, many times under identical conditions. the proportion of times a particular event occurs is recorded. this proportion represents a. the variance of the event. b. the distribution of the event. c. the correlation of the event. d. the probability of the event. (b) the collection of all possible outcomes of a random phenomenon is called a. the distribution. b. the sample space. c. the probability. d. a census. e. none of the above.

Explanation:

(a) Probability is defined as the proportion of times a particular event occurs when an experiment is repeated many times under identical conditions. Variance measures spread, distribution refers to how values are distributed, and correlation measures the relationship between variables.
(b) The sample - space is the set of all possible outcomes of a random phenomenon. Distribution is about how values are spread, probability is a measure related to events, and a census is a complete count of a population.

Answer:

(a) D. the probability of the event
(b) B. the sample space
