Answer

Brief Explanations:

The claim is that less than ½ of Americans are in favor. In hypothesis - testing, when the alternative hypothesis has a "<" sign, it is a left - tailed test. Here the alternative hypothesis would be $p<0.5$ (where $p$ is the proportion of Americans in favor), so the test is left - tailed.

Answer:

Left - tailed
