Test the following hypotheses given information below.
H 0 : µ = 42 and H 1 : µ > 42.
Assume the data was randomly obtained, and variable has an approximately normal distribution. From sample we are told that x-bar = 43.5 and s = 4. We are also told that n = 25.
Determine the appropriate test statistic to use?
Provide your value of test statistic you obtained.
What is your decision if the level of significance is ? = 0.1? Explain in <100 words how you came to this decision.
