Complete Question
For the hypothesis [tex]H_o : \mu = 4[/tex] test against [tex]H_a : \mu < 4[/tex]and variance known, calculate the P-value for the following test statistic [tex]z_o=1.645[/tex].
Round your answer to three decimal places (e.g. 98.765). P-value
Answer:
The p-value is [tex]p-value = 0.05[/tex]
Step-by-step explanation:
From the question we are told that
The test statistics is [tex]z_o=1.645[/tex]
Generally from the z -table the probability of [tex](Z < 1.645)[/tex] is
[tex]p-value = P(Z < 1.645 )= 0.05[/tex]
=> [tex]p-value = 0.05[/tex]
