a set of data with a mean of 245 and a standard deviation of 8.3 is normally distributed. Find the value that is +1 standard deviation away from the mean.
soo ... mean + 1(sd) they give you the mean and the sd ...
i mean the answer that they have on here is a.)28.4 b.)53.3 c.)36.7 d.)45.0
hmm, they prolly want the probabilty associated with 1sd from the mean
otherwise none of that makes sense :)
i believe so cause thats all its tell me and i dont get it
nope - 1 sd has 34.1 % of population. @blackasian Have you written question properly? is the mean 24.5? (Still wouldn't make sense - but I think you have not got the full info in your question...)
yeah, 68/2 is an approx or something like that
oh i have a typooo , it was the mean of 45 not 245
45 8.3 ----- 53.3 then adding them makes sense lol
Omg thankss so much . (;
