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, 5% had three, 16% had two, and 23% had one defect. Find the expected number of appearance defects in a new car and the standard deviation. 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.)
