Answer:
A) H0: Number of fatal accidents does not vary from month to month, HA: Number of fatal accidents does vary from month to month
Explanation:
1) Previous concepts
A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".
The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".
The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".
2) Solution to the problem
On this case we want to test if the number of fatal accidents which occur in her state does not vary from month to month
We need to take in count that on the alternative hypothesis never we can hav a symbol of equal or no variation, so based on this the correct system of hypothesis for this case would be:
Null hypothesis: Number of fatal accidents does not vary from month to month
Alternative hypothesis: Number of fatal accidents does vary from month to month
The best option is:
A) H0: Number of fatal accidents does not vary from month to month, HA: Number of fatal accidents does vary from month to month
