Find the mean for each data set. 1) 46.2 62.8 64 9.6 21.8 29.6 65 58.6 15.6 40.4 28.8 32.2 57.8 53.4 58.6

mean is 42.96

Step-by-step explanation:

to find the mean(average), add all the numbers up and divide by how many numbers there are:

46.2+62.8+64+9.6+ 21.8+ 29.6 +65+ 58.6 +15.6 +40.4+ 28.8+ 32.2 +57.8 +53.4 +58.6=644.4

644.4/15=42.96
