Let \(\rm \overline x\) : mean of x1, x2, ..., xn. If xi = a + d yi, for some constants a and d, then \(\rm \overline y\) will be
1
\(\rm \overline y={ \overline x\ +\ a\over d}\)
2
\(\rm \overline y={1\over n}{ \overline x\ +\ a\over d}\)
3
\(\rm \overline y={1\over n}{ \overline x\ -\ a\over d}\)
4
\(\rm \overline y={ \overline x\ -\ a\over d}\)
