-6 < 3x
-2 < x

B. Reject the claim that the proportion of Americans that have seen a UFO is equal to 2 in a thousand when that proportion is actually 2 in a thousand
Step-by-step explanation:
The type I error is rejection of true null hypothesis.
In the given scenario our hypothesis are
Null hypothesis: The proportion of Americans that have seen a UFO is equal to 2 in a thousand.
Alternative hypothesis: The proportion of Americans that have seen a UFO is less than 2 in a thousand.
Type I error is the rejection of true null hypothesis so, in this case type I error is rejection of claim that the proportion of Americans that have seen a UFO is equal to 2 in a thousand when that proportion is actually 2 in a thousand.
