Answer:
Step-by-step explanation:
Given
See attachment for complete question
Required
From the attachment, we have:
---- the sample size
Next, we list out all outcomes more than or equal to 5.
i.e.
5 is represented with the vertical blue rectangle (with frequency 21).
So, the other elements are to the right of frequency 21.
So, we have:
The probability is then calculated as:
This gives
Answer:
The question is incomplete, so I will describe the sine regression model.
The function
y = 0.884 sin(0.245x - 1.093) + 0.400
correspond to the general equation:
y = a sin(bx - c) + d
where:
a = 0.884
b = 0.245
c = 1.093
d = 0.400
The amplitude of the function is computed as follows:
amplitude = |a| = 0.884
The period of the function is computed as follows:
period = 2π/|b| = 25.6456
The phase shift of the function is computed as follows:
phase shift = c/b = 4.4612 to the right (because there is a minus sign before c in the equation)
The vertical shift of the function is computed as follows:
vertical shift = d = 0.400
