Some smells are perceived as being more feminine or more masculine. Researchers asked a random sample of 300 American adults to score quantitatively the perceived gender-orientation of lavender. Smaller scores indicate a more feminine scent and larger scores a more masculine scent. In this design, a gender-neutral scent would have a perceived gender-orientation score of 12. The participants gave the scent of lavender an average score of 10.28.Is this evidence that the scent of lavender is not gender‑neutral, on average? Select the correct statement of H0H0 , HaHa , and the hypotheses parameter in the corresponding test. - Let µμ be the mean gender‑orientation score for all smells being studied. We test H0:µ=12H0:μ=12 versus Ha:µ≠12Ha:μ≠12 ; The alternative is two‑sided because we want to test if all of the smells are not gender‑neutral. - Let µμ be the mean gender‑orientation score for lavender. We test H0:µ=1.28H0:μ=1.28 versus Ha:µ≠10.28Ha:μ≠10.28 ; The alternative is two‑sided because we want to test if lavender is not gender‑neutral. - Let µμ be the mean gender‑orientation score for lavender. We test H0:µ=12H0:μ=12 versus Ha:µ≠12Ha:μ≠12 ; The alternative is two‑sided because we want to test if lavender is not gender‑neutral. - Let µμ be the mean gender‑orientation score for lavender. We test H0:µ<12H0:μ<12 versus Ha:µ≥12Ha:μ≥12 ; The alternative is not two‑sided because we want to test if lavender is gender‑neutral.
