Multiple Choice

SCENARIO 9-3
An appliance manufacturer claims to have developed a compact microwave oven that consumes a mean of no more than 250 W.From previous studies, it is believed that power consumption for microwave ovens is normally distributed with a population standard deviation of 15 W.A consumer group has decided to try to discover if the claim appears true.They take a sample of 20 microwave ovens and find that they consume a mean of 257.3 W.
-Referring to Scenario 9-3, the appropriate hypotheses to determine if the manufacturer's claim appears reasonable are:

• A)\(H _ { 0 } : \mu = 250 \text { versus } H _ { 1 } : \mu \neq 250\)
• B)\(H _ { 0 } : \mu \geq 250 \text { versus } H _ { 1 } : \mu < 250\)
• C)\(H _ { 0 } : \mu \leq 250 \text { versus } H _ { 1 } : \mu > 250\)
• D)\(H _ { 0 } : \mu \geq 257.3 \text { versus } H _ { 1 } : \mu < 257.3\)
