Let test statistic of a data be represented by :
$t=\frac{(0.742-0.7)}{0.04}×3=3.15$ and it is given that $t_9(0.05)=2.267;$ then select the correct option :
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → \( t=3.15 > t_9(0.05)\);then null hypothesis is not accepted
The computed t-value is, $t=3.15$
Critical t-value, $tg(0.05)=2.267$
$t>tg(0.05)$, the test static is greater than the critical value, which means we reject the hypothesis.
