Do you mean n = 42 (sample size) and (sample mean) ? And s = 0.44?
Can you define exactly what s ( .44) means please .... If it means what I think it means, then the answer you want is contained in your question ....
yes n is the sample size but the little s is not standard deviation, it said the standard deviation was the little circle with a line on the top of it, i can't remember the name of it
