Answer:
(1) Correct option is B.
(2) Correct option is C.
Step-by-step explanation:
The information provided is:
The (1 - <em>α</em>)% confidence interval for the difference between two mean is:
The critical value of <em>t</em> is:
degrees of freedom 
Compute the 95% confidence interval for the difference between two mean as follows:
Thus, the 95% confidence interval, (2.14, 3.86) implies that the true mean difference value is contained in this interval with probability 0.95.
Correct option is B.
The null value of the difference between means is 0.
As the value 0 is not in the interval this implies that there is a difference between the two means, concluding that priming does have an effect on scores.
Correct option is C.

Answer:
Height = 11 inches
Base = 33 inches
Step-by-step explanation:
In this question, we are asked to find the height and base of a parallelogram given the area of the parallelogram.
From the question, we are told that height is 1/3 of base. This means that base is 3 times the height
So if we represent the height with variable h, then the base is 3h
Mathematically the area of a parallelogram can be calculated by the formula
A = bh
Thus ,
363 = h * 3h
3h^2 = 363
divide through by 3
h^2 = 121
h = √121
h = 11 inches
since b = 3h , then b = 3 * 11 = 33 inches
Answer: The answer is -2
Step-by-step explanation:
To make this easier, first draw or imagine a vertical line at x=2
Find where the vertical line and the graph intersects.
Draw or imagine that point of intersection.
Now, draw or imagine a horizontal line that goes through the point of intersection.
That horizontal line tells us the the value of the function by passing through that mark that says "-2"
The function's value at x=2 is -2.
