Answer:
The most appropriate inference procedure for the investigation is;
a. A linear regression t-interval for the slope
Step-by-step explanation:
Given that the slope of an horizontal line is zero, we have that there is no change in the y (dependent) variable when there is a change in the x-variable, therefore, it is important to find the true relationship between the two variables, 'x', and 'y'
The confidence interval of the slope is calculated and analyzed to determine if it excludes or includes, 0, such that, if the confidence interval exclude 0, then, it is unlikely that the slope is 0, therefore, there the relationship between the variables, 'x', and 'y' is significant
Therefore, a linear regression t-interval for the slope is most appropriate.
Answer:
7
Step-by-step explanation:
Amplitude is the positive multiple of sin(theta) which is 7 here.
Answer:
vertical asymotote at 
Step-by-step explanation:

vertical asymptote is the line where the graph goes close to the line but does not cross it.
To find vertical asymptote, we set the denominator =0 and solve for x
denominator is 3x+2
set 3x+2=0
Subtract 2 on both sides

divide both sides by 3
