Final answer:
The significance level for a right-tailed test at 6 percent is 6 percent.
Step-by-step explanation:
The significance level for a right-tailed test is the probability of obtaining a test statistic that is as extreme as, or more extreme than, the observed value, assuming the null hypothesis is true. In this case, the significance level is given as 6 percent. Since the null hypothesis is assumed to be true, the right tail corresponds to values greater than the observed value. Therefore, the significance level is the probability of obtaining a test statistic that is greater than the observed value, which is 6 percent.
