The intensity of light is measured in foot-candles or in lux. In full daylight, the light intensity is approximately 10,700 lux, and at twilight the light intensity is about 11 lux. The recommended level of light in offices is 500 lux. A random sample of 50 offices was obtained and the lux measurement at a typical work area was recorded for each. The data are given in the following table: 468 497 503 529 435 481 520 521 536 492 509 516 503 481 562 474 514 488 508 495 536 504 514 471 458 494 519 511 490 450 482 514 475 526 463 520 487 506 464 482 531 486 518 495 497 492 519 466 520 499 By constructing a stem-and-leaf plot for these light-intensity data, where each stem consists of hundreds and tens digits and each leaf consists of ones digit (e.g., for datum 499, stem is 49 and leaf is 9), is there any outlier in the data set?
