Statistics: Given H0: µ = 18 and p-value = 0.070.

Question

Given H0: μ ≥ 18 and p-value = 0.070. Do you reject or do not reject H0 at the 0.05 level of significance?

 

 

A.not enough information to decide 

 

B.do not reject H0

 

C. reject H0

 

 

The correct answer is B i just do not know how to find it 

Answer 1

Think about how the p-value is calculated.  The p-value is computed assuming that H0 is true, and is simply the probability that the observed outcome would take a value as extreme or more extreme than what was actually observed in the sample data.  The smaller the p-value is, the stronger the evidence against H0 provided by the data.  If the p-value is high (in particular, if it is higher than the level of significance) then the data does not provide strong evidence against H0 and H0 cannot be rejected.
