I have to write a null hypothesis and the alternative hypothesis. Then, label the one that is the claim being?

made. A taxi cab drivers union clains that the mean age of a bus-driver is 55.3.


Am I on the right track?


Null hypothesis is that the taxi driver union is claiming that the mean age of driver's is 55.3 years of age.


Alternative hypothesis would be the dispute that the taxi driver's are less than 55.3 yrs of age (maybe a mean age of 34) or older than 55.3 yrs of age (maybe a mean of 60)|||You are on the right track:





The null hypothesis that the mean of our sample will equal the expected value based on the claim.





X(bar) = 55.3





The alternative hypothesis is the negation of this null hypothesis:





X(bar) %26lt;%26gt; 55.3|||The null hypothesis states that there will be no statistacally significant difference between the mean age of the drivers and 55.3. The alternative hypothesis is that there WILL be a significant difference between the mean age and the value of 55.3 (either higher or lower).
