Below is a distribution of insurance claims based on adverse events in a given year in Minnesota. Find the standard deviation of the value of insurance claims. Hint: Think how you can calculate the standard deviation of a random variable using the possible values it can take (e.g., “Claims value” below) AND the probability of each value (e.g., “Probability” below). Event Probability Claims value Tornado 0.10 $100,000 Flood 0.05 $40,000 Hail 0.05 $10,000 No event 0.80 $0

An LCC instructоr nоtices thаt students whо tаke lecture notes on their lаptops tend to perform worse in her class compared to students to take notes by hand. She hypothesizes that the act of taking notes on a computer leads to reduced retention of information compared to taking notes by hand. To test her hypothesis, she recruits 50 undergraduates from her institution to take part in a study. Participants are randomly assigned a note-taking strategy (either by hand or on a computer). They are led into an empty classroom and are instructed to take notes as they watch a 15-minute pre-recorded lecture. The following day, the participants are asked to return, and are given a quiz on the content of the lecture. Which of the following is the independent variable in this experiment? [a1] Which of the following is the dependent variable in the experiment? [a2] What are the experimental units in this experiment? [a3] Which of the following is least important for the instructor to control (hold constant)? [a4] Which of the following ideas for increasing replication is most likely to improve the ability to test the hypothesis that taking notes by hand leads to better retention of information compared to taking notes on a computer? [a5]
