25,55,40,65,29,45,59,35,25,37,52,30,8,40,55 find the standard deviation and mean
Go online and use this Stat. Calculator to get the answers you want:
Mean is the 40 because (25+55+40+65+29+45+59+35+25+37+52+30+8+40+55)/15=40
Standered deviation is 14.9086104875 because (25-40)^2=225 (Then do this for all the numbers you have) and then add them together, divide by 15 and take the square root.
