Answer 1

Answer #1

Answer:

Provided information

$\alpha$ =0.1 And Z-statistic=-3.4

Critical value =± 1.645

And

P-value =P(|Z|> |-3.4|)=P(|Z|>3.4)

P-value=0.000674

P-value is less than $\alpha$ =0.1 also Z is less than -1.645

Decision: Rejected Null Hypothesis

Thank you!

Please thumbs up?
