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.

Iam stuck on one problem. my mind is in absoloute vacation mode. i literallty just need to finish this to be done will give brainliest and all my points if i have to! 1- point free throw and 2- point feild goal. he made 35 shots, and scored 62 points how many of each shot did he make in 1 minute? (i already did the math. he made 8 1-point free throws and 27 2-point feild goals.) 1. write two equations for the problem. (i had a major brain fart.)
