STATISTICS QTN/375 Sophia Introduction to Statistics Unit 3 Milestone (AutoRecovered ) Updated 2022 The average number of tunnel construction projects that take place at any one time in a certain state is 3. Find the probability of exactly five tunnel construction projects taking place in this state.  0.023  0.048  0.10  0.020 Question 2 Mark this question Kate was trying to decide which type of frozen pizza to restock based on popularity: pepperoni pizza or sausage pizza. After studying the data, she noticed that pepperoni flavors sold best on the weekdays and on the weekends, but not best overall. Which paradox has Kate encountered?  False Negative  Benford's Law  False Positive  Simpson's Paradox Question 3 Mark this question Using the Venn Diagram below, what is the conditional probability of event Q occurring, assuming that event P has already happened [P (Q|P)]?  0.75  0.73  0.05  0.55 Question 4 Mark this question Sarah throws a fair die multiple times, recording the total number of "2"s she throws and then calculating the proportion of "2"s she has thrown so far after each throw. She then constructs a graph to visualize her results. Which of the following statements is FALSE?  The theoretical probability of getting a 2 is 0.167 for each throw.  This is an example of the law of large numbers.  The probability distribution for the possible number of outcomes changes as the total number of throws increases.  The relative frequency of "2"s thrown changes as Sarah throws the die more. Question 5 Mark this question Which of the following is an example of a false positive?  Test results confirm that a patient does not have cancer.  Test results indicate that a patient has cancer when, in fact, he does not.
