I test the hypothesis H0 0 against HA 0 The sample mean is

I test the hypothesis H₀: = 0 against H_A: 0. The sample mean is x = 2 and p-value is 1.2%. What is the p-value for the hypothesis H₀: 0 against H_A: > 0?

A) 98.6%

B) 50%

C) 1.2%

D) 0.6%

E) 99.4%

Please show the work and not just the final answer alone!

Solution

The sample mean is x = 2 and p-value is 1.2%

fonr two tail p value=0.012

and forn one tail =(0.12 / 2) =0.006

Hence P value for one tail is 0.006
