You wish to determine which of two brands of TVs is more expensive. You conduct the following sample, which suggests that Orion TVs are more expensive: Orion: ē = $318, 8 = 12.6, n = 30 Luna: ā = $313, s2 = 15.1, n = 25 Define your variable: O Let p be the proprotion Orion TVs in the sample that cost more than Luna TVs. O Let u be the mean price of TVs, in dollars O Let mu the mean price of Orion TVs, in dollars. O Let u be the mean price of sampled TVs, in dollars. Write your hypotheses: Be sure to chose Group 1 to have the larger sample mean. Но: Opi – p2 = 0 Opi – p2 = 318 – 313 O u1 – 42 = 5 O µi - µ2 = 0 HA: µi - µ2 > Ομ- μ<0 O µi – 42 = 5 Opi – P2 = 318 – 313

Find the P-value: Type your answer as a decimial rounded to three decimal places. Do not type a percentage or a percent sign. P-value= Using an a level of 5%, you should O Fail to Reject Ho Reject H, and Accept HA O Accept Ho State your conclusions: We do do not have strong evidence that the the proportion of Luna TVs that are expensive is more than the proportion of Orion TVs that are expensive. O the mean price of sampled Orion TVs is more than the mean price of sampled Luna TVs. the mean price of Orion TVs is more than the mean price of Luna TVs. the mean price of Luna TVs is more than the mean price of Orion TVs. Othe proportion of Orion TVs that are expensive is more than the proportion of Luna TVs. You would rather purchase an Orion TV, but only if you are convinced that they are not more expensive than Luna TVs. Based on your results above, would you bother looking into pricing Orion TVs? Yes O No

You wish to determine which of two brands of TVs is more expensive. You conduct the following sample, which suggests that Orion TVs are more expensive: Orion: ā = $318, sª = 12.6, п — 30 Luna: ā = $313, 8z = 15.1, n = 25 Define your variable: O Let p be the proprotion Orion TVs in the sample that cost more than Luna TVs. OLet u be the mean price of TVs, in dollars Let mu the mean price of Orion TVs, in dollars. Let u be the mean price of sampled TVs, in dollars. Write your hypotheses: Be sure to chose Group 1 to have the larger sample mean. Но: Opi – P2 = 0 O pi – P2 = 318 – 313 Ο μ-μ 5 µi - µ2 = 0 HA: Hi – µ2 > 0 O ui – u2 < 0 µi – µ2 = 5 Opi - - P2 = 318 – 313
