Explanation / Answer

It is a two tailed hypothesis testing where we want to test whether the average score in cincinati area is equal to the state average in mathematics or not equal to state averae in mathematics.

so, we can see this from the data table that the p value obtained from the hypothesis testing is equal to 0.1480 which is insignificant at 0.01, 0.05 or 0.10 level of significance, thus we fail to reject the null hypothesis becauuse the p value is more than alpha levels.

So, we can conclude that the average score in cincinati area is equal to the state average in mathematics because p value is insignificant.
