Consider a test of $\mathrm { H } _ { 0 } : \mu = 80$ performed with the computer. SPSS reports a two-tailed p-value of $0.0070$. Make the appropriate conclusion for the given situation: $\mathrm { H } _ { \mathrm { a } } : \mu \neq 80 , z = 2.7 , \alpha = 0.01$
A) Fail to reject $\mathrm { H } _ { 0 }$
B) Reject $\mathrm { H } _ { 0 }$

The p-value of 0.0070 is less than the significance level $\alpha = 0.01$, indicating strong evidence against the null hypothesis $\mathrm { H } _ { 0 } : \mu = 80$, leading to the rejection of $\mathrm { H } _ { 0 }$.
