(i) H0: u>=128
this is left tail test.
(ii) H0: u>=50,000
this is also left tail test.
this is right tail test.
Hey I'm learning about Hypothesis test this week and the way my teacher explained it was very confusing. So I was wondering if i post a question and the answer I get could someone tell me if I did it right or not. Thank You.
For this problem I need to write its complement and which is Ho and Ha. the problem is u<128
I got Ha= u<128 and Ho= u > 128.
For this problem I need to determine wither the hypothesis test is tailed to the left, right or both. the problem is-The mean life of a certain tire is no less than 50,000 miles.
My answer is u > 50,000 and is tailed to the left.
The problem for this one is- A taxicab comp. claims that the mean travel time between 2 destinations is about 21 min. You work for a bus comp. and you reject this claim. How would you write the null and alternative hypthesis?
My answer is Ho= u> 21 min. and Ha= u>21 min
Thank you to whom responds I'm not sure if I'm doing this write.
