A transportation organization claims that the mean travel time between two destinations is about 23 minutes. Write the null and alternative hypotheses and note which is the claim.
Ho: μ = 23 (claim), Ha: μ ≤ 23
Ho: μ ≠ 23, Ha: μ = 23 (claim)
Ho: μ = 23 (claim), Ha: μ ≠ 23
Ho: μ > 23, Ha: μ ≤ 23 (claim)
Homework Answers
solution:
this is the two tailed test .
The null and alternative hypothesis is ,
H0 : 
= 23
Ha :
23
Ho: μ ≠ 23, Ha: μ = 23 (claim)
