Hi i need some help, Im asked to use the 7 STEP HYPOTHESIS TESTING for the information given above..could someone please help me out, it would be greatly appreciated.
Solution
Ho : miu = 18
H1 : miu not equal 18
critical values for alpha = 0.05
Z= +/- 1.96
Decision rule
Reject Ho if Z test is greater than critical value
Fail to Reject Ho if Z test is lower than critical value
Ztest = 18 - 17 / ( 3.5356 / sqrt (5))
Z test = 0.63
CONCLUSION
FAIL TO REJECT Ho BECAUSE Z TEST < CRITICAL VALUE
