The average number of times a person presses the snooze button in the morning is 4 times. A pharmaceutical company believes this is not correct. What is the alternative hypothesis?
a) $\mu=4$
b) $\mu \neq 4$
c) $\mu> 4$
d) $\mu< 4$
Answer
Final Answer: The alternative hypothesis is \( \boxed{\mu \neq 4} \)
Step 1 ：The question is asking for the alternative hypothesis. In hypothesis testing, the alternative hypothesis is what you might believe to be true or hope to prove true.
Step 2 ：The pharmaceutical company believes that the average number of times a person presses the snooze button in the morning is not 4 times.
Step 3 ：Therefore, the alternative hypothesis should be that the mean is not equal to 4.
Step 4 ：Final Answer: The alternative hypothesis is \( \boxed{\mu \neq 4} \)
