Question

Hi, can you help me answer this question please, thank you!

Answer 1

`p-value=0.0076`

Explanation:

We must calculate the value of p from the value of z, we will do it with the help of the following table:

Knowing that the value p is P (z> 2.428), which due to the symmetry of the normal distribution is equal to P (z <-2.428) (According to the table, we can obtain the value of p:

`\begin{gathered} P(z<-2.428)\cong0.0076 \\ p-value=0.0076 \end{gathered}`
