Data will be collected to test the hypothesis that the majority of all americans are in favor of building new nuclear power plants. the level of significance was 0.10. if it is indeed true that exactly half the us population is in favor of building new nuclear power plants, then there is a 10% chance that the null hypothesis will be rejected. t/f

The correct answer is "True".

Explanation:

The alternative hypothesis of this study is that the majority of all Americans are in favor of building new nuclear plants. Therefore, the null hypothesis is that exactly or less than half the population is in favor of building new nuclear plants. Since the level of significance was 0.10 it is true that there is there is a 10% chance that the null hypothesis will be rejected if exactly half of the Americans are in favor. The level of significance is defined as the probability of rejecting a null hypothesis, and the value of 0.10 accounts for 10% of probability.
