Null hypothesis: H0: The dictator's negative are equal to 70%.

Alternative hypothesis: Ha: The dictator's negative are less than 70%.

Step-by-step explanation:

The null hypothesis always contains equality sign and alternative hypothesis usually contains claim made by researcher. Here, in the given scenario, the political committee of a dictator wants to keep negatives below to 70%. So, the null hypothesis will be that the negative are equal to 70% while alternative hypothesis will be that the negative are less than 70%.

Thus, the hypotheses for the given scenario are

Null hypotheses: H0: The dictator's negative are equal to 70%.

Alternative hypotheses: Ha: The dictator's negative are less than 70%.
