Formulate the indicated conclusion in nontechnical terms. Be sure to address the original claim.
A skeptical paranormal researcher claims that the proportion of Americans that have seen a UFO, p, is
less than 2 in every ten thousand. Assuming that a hypothesis test of the claim has been conducted and
that the conclusion is failure to reject the null hypothesis, state the conclusion in nontechnical terms.
A. There is not sufficient evidence to support the claim that the true proportion is greater than 2 in
ten thousand.
B. There is not sufficient evidence to support the claim that the true proportion is less than 2 in ten
thousand.
O c. There is sufficient evidence to support the claim that the true proportion is greater than 2 in ten
thousand.
O D. There is sufficient evidence to support the claim that the true proportion is less than 2 in ten
thousand.
