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

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 -
