Question

Critical Value

Answer 1

Critical Value :In hypothesis testing, a critical value is a point on the test distribution which is compared with the test statistic to determine whether to reject the null hypothesis. If the absolute value of your test statistic is greater than the critical value,reject the null hypothesis and can say the it is statistical significant otherwise we willbe failed to reject the null hypothesis and conclude that it is not statistically significant.

Crtitcal value can dirrectly calculated against given level of significance alpha

alpha (α): α = 1 - confidence level

Critical value depends on the type of distribution(Z,T, F etc)

Note: it seems you dis not typed your answer completely but i cant see anything except Critical value.
