Question
![The drying time of a certain type of paint under specified test conditions is considered to be normally distributed witn µ=100 min and o=11 min.
It is suspected that the actual drying time is perhaps not equal to 100 min. and hence a hypothesis test is being arranged as
H0: u = 100
На: и #100
n=25 random samples have been collected and drying time measured for each.
Average drying time calculated from the samples is X-bar= 102.08 min
Answer the following questions for the aboove scenario.
Part (a)
What is your decision for the above hypothesis test if a error is maintained at 0.05?
Part (b)
What is the P-value for the test in part (a)
Part (c)
For test of hupothesis, Instead of using (X-bar-u0)/(0/sqrt(n)) as the test statistic if you use X-bar as the test statistic,
what would be the limits outside of which you will reject HO?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff966c414-4cbd-409b-9db4-c8010e535c33%2F9986d2c0-e146-4ad0-b77b-08fb7c7aa01c%2Fcgs9nk_processed.png&w=3840&q=75)
