Physical Sciences 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.17 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:

a. Construct a stem-and-leaf plot for these light-intensity data.
b. What is a typical light intensity? Are there any outliers? If so, what are they?
