A fish story: The mean length of one-year-old spotted flounder, in millimeters, is 120 with standard deviation of 19, and the mean length of two-year-old spotted flounder is 157 with a standard deviation of 27. The distribution of flounder lengths is approximately bell-shaped. Part 1 of 4 (a) Anna caught a one-year-old flounder that was 155 millimeters in length. What is the z-score for this length? Round the answers to at least two decimal places. Anna's z-score is Part 2 of 4 (b) Luis caught a two-year-old flounder that was 185 millimeters in length. What is the z-score for this length? Round the answers to at least two decimal places. Luis's z-score is Part 3 of 4 (c) Joe caught a one-year-old flounder whose length had a z-score of 1.3. How long was this fish? Round the answer to at least one decimal place.. The length of Joe's fish is millimeters.
