Answer:
66 minutes
Step-by-step explanation:
Method I - proportion
x/44 = 9/6
multiply both sides by 44
x = 9 / 6 * 44
x = 66 minutes
--------------------------
Method II - rate
44/6 = 7.3333333 minutes / mile
9 * 7.3333333 = 66 minutes
Answer:
567.52 m

Answer:
and ![H_{a}: \mu > 185](https://tex.z-dn.net/?f=H_%7Ba%7D%3A%20%5Cmu%20%3E%20185)
Step-by-step explanation:
The null hypothesis
states that a population parameter (such as the mean, the standard deviation, and so on) is equal to a hypothesized value. We can write the null hypothesis in the form ![H_{0}: parameter = value](https://tex.z-dn.net/?f=H_%7B0%7D%3A%20parameter%20%3D%20value)
In this context, the investigator's null hypothesis should be that the average total weight is no different than the reported value by the FAA. We can write it in this form
.
The alternative hypothesis
states that a population parameter is smaller, greater, or different than the hypothesized value in the null hypothesis. We can write the alternative hypothesis in one of three forms
![H_{a}: parameter > value\\H_{a}: parameter < value\\H_{a}: parameter \neq value](https://tex.z-dn.net/?f=H_%7Ba%7D%3A%20parameter%20%3E%20value%5C%5CH_%7Ba%7D%3A%20parameter%20%3C%20value%5C%5CH_%7Ba%7D%3A%20parameter%20%5Cneq%20value)
The investigator wants to know if the average weight of passengers flying on small planes exceeds the FAA guideline of the average total weight of 185 pounds. He should use
as his alternative hypothesis.
