table is a tabular summary of probabilities concerning two sets of complementary events. Answer: True Difficulty: Medium 2. An event is a collection of sample space outcomes. Answer: True Difficulty: Easy 3. Two events are independent if the probability of one event is influenced by whether or not the other event occurs. Answer: False Difficulty: Medium 4. Mutually exclusive events have a nonempty intersection. Answer: False Difficulty: Medium (REF)

MAT540 - Quantitative Methods (Homework # 2) Section A True/False Indicate whether the sentence or statement is true or false. __F__ 1. Two events that are independent cannot be mutually exclusive. __F__ 2. A joint probability can have a value greater than 1. __F__ 3. The intersection of A and Ac is the entire sample space. __T__ 4. If 50 of 250 people contacted make a donation to the city symphony‚ then the relative frequency method assigns a probability of .2 to the outcome of

Using the alphabetic characters B and R to represent the events “buying the product” and “recalling seeing the commercial” respectively‚ construct a 2x2 contingency/cross tabulation table to summarise the findings of the survey. 2. If the information revealed by the survey is typical of the population as a whole
