In a national poll of 1,714 people aged 45 andolder, 1,252 of respondents agreed with the statement,"Adults should be allowed to legally use marijuana for medicalpurposes if a physician recommends it." We want to use software totest if a majority (more than 0.5) of all people from a particularcountry aged 45 and older support legalization of marijuana formedical purposes.
(a) First identify
H0 and Ha.
H0: 𝜇 = 0.73vs. Ha: 𝜇 >0.73
H0: 𝜇 = 0.50vs. Ha: 𝜇 >0.50
H0: 𝜇 = 0.73vs. Ha: 𝜇 ≠ 0.73
H0: 𝜇 = 0.50vs. Ha: 𝜇 ≠ 0.50
H0: p =0.73vs. Ha: p >0.73
H0: p =0.50vs. Ha: p >0.50
H0: p =0.73vs. Ha: p ≠ 0.73
H0: p =0.50vs. Ha: p ≠ 0.50
H0: p˂ = 0.73vs. Ha: p˂ >0.73
H0: p˂ = 0.50vs. Ha: p˂ >0.50
H0: pĖ‚ = 0.73vs. Ha: pĖ‚ ≠ 0.73
H0: pĖ‚ = 0.50vs. Ha: pĖ‚ ≠ 0.50
(b) According to the output, what is the sampleproportion p˂? (Round your answer to two decimalplaces.)p˂ = (c) According to the output, what is the standardized sampleproportion z? (Round your answer to two decimalplaces.)z = (d) According to the output, what is the P-value?(Round your answer to three decimal places.)(e) Does the poll provide convincing evidence that a majority ofpeople aged 45 and older support legalization of marijuana formedical purposes?
Yes, with strong evidence.Yes, but justbarely. No, not quite.No, not at all.
