Question

When you encounter a T-critical value of 2.50, which T-obtained value would reject the null hypothesis? A) Tobt = 2.75 B) Tobt = -2.75 C) Tobt = 2.40 D) Tobt = - 2.40

Answer 1

Answer: A) Tobt = 2.75 B) Tobt = -2.75

Explanation:

• We reject the null hypothesis when the absolute critical t-value is lower than the absolute t-obtained value.

The given t-critical value $T_{crit}=2.50$

So , we reject null hypothesis , when $2.50< | T_{obt}|$

Since, $2.50<|2.75|,\ \ 2.50<|-2.75|$  but $2.50>|2.40|\ \ \ , 2.50>|-2.40|$

So, the correct options are A) Tobt = 2.75 B) Tobt = -2.75
