Hi, I'm almost at the end of a question but i seem to be stuck. I have the answer though.. so im up to here so can someone please help me complete this:(adsbygoogle = window.adsbygoogle || []).push({});

[tex] (\frac{n + \frac{1}{c}}{\frac{s}{n} }) [\mu^2 - 2\mu(\frac{n \overline{y}}{n+\frac{1}{c}})] [/tex]

then i completed the square:

[tex](\frac{n + \frac{1}{c}}{\frac{s}{n} }) [(\mu - \frac{n\overline{y}}{n + \frac{1}{c}})^2 - (\frac{n\overline{y}}{n + \frac{1}{c}})^2][/tex]

then i expanded it:

[tex] (\frac{n + \frac{1}{c}}{\frac{s}{n} })(\mu - \frac{n\overline{y}}{n + \frac{1}{c}})^2 - (\frac{n + \frac{1}{c}}{\frac{s}{n} })(\frac{n\overline{y}}{n + \frac{1}{c}})^2 [/tex]

then i guess:

[tex] (\frac{n + \frac{1}{c}}{\frac{s}{n} })(\mu - \frac{n\overline{y}}{n + \frac{1}{c}})^2 - [/tex][tex] (\frac{n + \frac{1}{c}}{\frac{s}{n} })(\frac{1}{(\frac{n\overline{y}}{n + \frac{1}{c}})^2 })[/tex]

and then i tried really hard to simplify it but i cant get the answer...

then answer is:

[tex]\frac{n + \frac{1}{c}}{\frac{s}{n} + \frac{\overline{y}(\frac{1}{c})}{(n + \frac{1}{c})}}[\mu - (\frac{n\overline{y}}{n + \frac{1}{c}})]^2[/tex]

am i doing it right so far? and if so, then can you please help me figure out the next line, coz i tried and i cant somehow get that answer..:(.. thank you..?
