Describe how to graph point K at (5,4)
2 answers:
Answer & Step-by-step explanation:
Remember this:
When you are going to graph a point, you always start along the x-axis (the horizontal), then you move on to the y-axis (vertical). Both of the numbers in K are positive, so we will stay in Quadrant I.
For x, starting at (0,0) move to the right to point 5. From here, move up to the line that has value 4. Mark this spot with a dot and label if needed.
*If the x value is positive, you move to the right. If it is negative, you move to the left.
If the y value is positive, you move up. If it is negative, you move down.

For this case what you should know is that both functions are of the potential type.
We have then that
y = 2 * 2 ^ x
This function grows exponentially upwards.
y = -2 * 5 ^ x
This function grows exponentially downwards.

Answer:
The 98% confidence interval for the true difference between testing averages for students using Method 1 and students using Method 2 is (-8.04, 0.84).
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for the difference between population means is:
The information provided is as follows:
The critical value of <em>z</em> for 98% confidence level is,
Compute the 98% confidence interval for the true difference between testing averages for students using Method 1 and students using Method 2 as follows:
Thus, the 98% confidence interval for the true difference between testing averages for students using Method 1 and students using Method 2 is (-8.04, 0.84).
