Question 483926: • State the null hypothesis Ho and the alternative hypothesis Ha that would be used for a hypothesis test related to each of the following statements:
o a. The mean age of the students enrolled in evening classes at a certain college is greater than 26 years.
o b. The mean weight of packages shipped on Air Express during the past month was less than 36.7 lb.
o c. The mean life of fluorescent light bulbs is at least 1600 hours.
o d. The mean strength of welds by a new process is different from 570 Ib per unit area, the mean strength of welds by the old process
Thank you very much
You can put this solution on YOUR website! State the null hypothesis Ho and the alternative hypothesis Ha that would be used for a hypothesis test related to each of the following statements:
o a. The mean age of the students enrolled in evening classes at a certain college is greater than 26 years.
Ho: u <=26
Ha: u > 26
--------------------
o b. The mean weight of packages shipped on Air Express during the past month was less than 36.7 lb.
Ho: u >= 36.7
Ha: u < 36.7
--------------------
o c. The mean life of fluorescent light bulbs is at least 1600 hours.
Ho: u >= 1600
Ha: u < 1600
--------------------
o d. The mean strength of welds by a new process is different from 570 Ib per unit area, the mean strength of welds by the old process.
Ho: u = 570
Ha: u is to equal to 570
=================================
The Key idea in setting up Ho and Ha:
The equal sign must ALWAYS appear in Ho.
