NEED HELP in Chi Square


Can anyone please explain to me in reading # 11 Hypothesis, P 326 Schweser notes, in the solution of Chi Square, when we are putting values in the formula, I understand everything except the sample variance s2 -->. β€œ0.001444” where is this number coming from?

Thanks :slight_smile:

Hey there.

It comes from the previous page: s2 = 3.8% x 3.8% (squared sample variance).

LOLL. OMGG …thanks :slight_smile:
