Final answer:
The null hypothesis assumes that the mean repair bill of cars is $110 or less, while the alternative hypothesis assumes that the mean repair bill is greater than $110.
Step-by-step explanation:
To test the statement that the mean repair bill of cars is greater than $110, we can set up the null and alternative hypotheses:
- Null Hypothesis (H0): The mean repair bill of cars is <= $110
- Alternative Hypothesis (Ha): The mean repair bill of cars is > $110
In hypothesis testing, the null hypothesis is typically the statement that is being tested and the alternative hypothesis is the claim that we are trying to find evidence for. In this case, the null hypothesis assumes that the mean repair bill of cars is $110 or less, while the alternative hypothesis assumes that the mean repair bill is greater than $110.
