Question

A skeptical paranormal researcher claims that the proportion of Americans that have seen a UFO is less than 1 in every one thousand. State the null hypothesis and the alternative hypothesis for a test of Significance. A) $ \mathrm{H}_{0}: \mathrm{p}=0.001 $ $\mathrm{H}_{\mathrm{a}}: \mathrm{p}>0.001$ B) $ \mathrm{H}_{0}: \mathrm{p}=0.001 $ $\mathrm{H}_{\mathrm{a}}: \mathrm{p}<0.001$ C) $ \mathrm{H}_{0}: \mathrm{p}>0.001 $ $\mathrm{H}_{\mathrm{a}}: \mathrm{p}=0.001$ D) $ \mathrm{H}_{0}: \mathrm{p}<0.001 $ $\mathrm{H}_{\mathrm{a}}: \mathrm{p}=0.001$

Quizplus · Accepted Answer

The null hypothesis ($ \mathrm{H}_{0} $) assumes the proportion is equal to 0.001, while the alternative hypothesis ($ \mathrm{H}_{a} $) reflects the researcher's claim that the proportion is less than 0.001.
