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
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
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.
The dimensions of the rectangle given are
length = 14 meters
Width = 8 meters
The perimeter of the rectangle is given by the sum of its sides
The rectangle has to opposite sides of 14 meters and two opposite sides of 8 meters
Hence adding up the 4 sides we get
Hence option B is the right answer
