Teacl smolts are young salmon at a stage when their skin becomes covered with silvery scales and they start to migrate from freshwater to the sea. the reflectance of a light shined on a smolt's skin is a measure of the smolt's readiness for the migration. here are the reflectances, in percents, for a sample of 50 smolts. 57.6 54.9 63.4 57.1 54.8 42.4 63.5 55.5 33.6 63.2 58.3 42.0 56.0 47.7 56.2 56.0 38.7 49.6 42.2 45.7 69.1 50.5 53.0 38.3 60.4 49.2 42.8 44.6 46.3 44.2 59.0 42.0 47.6 47.9 69.2 46.6 68.0 42.9 45.5 474 59.5 37.7 53.9 43.1 51.3 64.6 43.7 42.7 50.9 43.8 (a) find the standard deviation of the reflectance for these smolts. (round your answer to two decimal places.) (b) find the quartiles of the reflectance for these smolts (c) do you prefer the standard deviation or the quartiles as a measure of spread for these data? give reasons for your preference.
