A consumer organization inspecting new cars found that many had appearance defects (dents, scratches, paint chips, etc.). While none had more than three of these defects, 9% had three, 19% had two, and 27% had one defect. Find the expected number of appearance defects in a new car and the standard deviation. Compute the expected value of the number of appearance defects. E(appearance defects) = (Round to two decimal places as needed.) Compute the standard deviation of the number of appearance defects. SD(appearance defects) = (Round to two decimal places as needed.) Indicate if the following represents independent events. Explain briefly. Measurements of the heart rates of all students in the gym Choose the correct answer below. A. Independent, because the outcome of one trial doesn't influence or change the outcome of another. B. Independent, because the outcome of one trial does influence or change the outcome of another. C. Not independent, because the outcome of one trial doesn't influence or change the outcome of another. D. Not independent, because the outcome of one trial does influence or change the outcome of another.
