Answer:
Step-by-step explanation:
Median. Median in this case will give the most meaningful information about this data set.
<em>Reason</em>: There is at least one extreme score,32, in the distribution. It is an outlier that has a great effect on the mean:-
Hence median will give the most meaningful info about this data set
The sinusoidal function that models the situation is:
From the function, we have that:
- The amplitude is of 4.5 ft.
- The mid-line equation is of y = 5.
A sinusoidal function is a trigonometric function, and has the following format, considering no phase shift:
In which:
- A is the amplitude, which is the twice the difference between the largest and smallest value.
- The period is of
.
- C is the vertical shift, and the mid-line equation is
.
In this problem, the high is of 9.5 ft and the low is of 0.5 ft, hence, for the amplitude, we have that:
With an amplitude of 4.5, the standard function would vary between -4.5 ft and 4.5 ft, while in this problem the variation is from 0.5 ft to 9.5 ft, hence the vertical shift is of:
Which means that the mid-line equation is of y = 5.
Period of 24 hours, hence:
Hence, the function is:
