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

Step-by-step 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
