Answer:
a. x = 40 wpm
b. MOE = 4.4 wpm.
c. If you were to create many more confidence intervals from many different random samples, you would expect 95% all of the confidence intervals to have centers and widths that include the true mean.
d. About 5% of the confidence intervals would not capture the parameter (true mean) you are trying to estimate.
Step-by-step explanation:
We have a 95% confidence interval for the mean with bounds 35.6 and 44.4.
This is estimated from a sample that, in this case, has a sample size of n=54.
The value of x, used to construct the interval, will be at the center of the interval. Then we can calculate the value of x as the average between the two bounds:
The margin of error is equal to the difference between x and any of the bounds:

d. About 5% of the confidence intervals would not capture the parameter (true mean) you are trying to estimate.
Answer:
623 is the answer
Step-by-step explanation:
equation : 8X-1
8(1)-1 = 7
8(2)-1 = 15
8(3)-1 = 23
8(4)-1 = 31
8(78)-1 = 623

Answer:
<em>JONATHAN WILL NEED 14 PAGES.</em>
Explanation:
<em>33 + 67 = 100</em>
<em>100 - 12 = 88</em>
<em>88 ÷ 6 = 14.6666667 </em>
<em>14.6666667 ⇒ </em><u><em>14</em></u>
<em>(Round 14.6666667 down to 14 because Johnathan does not have .6666667 of a page.)</em>

There are 4 quadrants in a coordinate plane
- The starting point is in the second quadrant, while the finishing point is in the fourth quadrant.
- The starting point is a reflection of the checkpoint across the y-axis
<u>Part A</u>
The points are given as:
For the starting point, the x-coordinate is negative, while the y-coordinate is positive.
This implies that the starting point is in the second quadrant
For the finishing point, the x-coordinate is positive, while the y-coordinate is negative.
This implies that the finishing point is in the fourth quadrant
<u>Part B</u>
The checking point is given as:
The starting point is given as:
Notice that the y-coordinate of both points are the same, but the x-coordinates are negated.
This means that the starting point is a reflection of the checkpoint across the y-axis, and vice versa
