Answer:
92% Confidence Interval = [8.515, 8.605]
Step-by-step explanation:
The number of samples given is 15,this less than 30, hence, we use the t score confidence Interval
= Mean ± t score × Standard deviation/√n
Mean = 8.56 ounces
Standard deviation = 0.09 ounces
n = 15
We find the degrees of freedom = n - 1
= 15 - 1 = 14
Using the T score table
T score for 92% confidence interval with degrees of freedom 14
= 1.8875
Hence:
Confidence Interval =
= 8.56 ± 1.8875 × 0.09/√15
= 8.56 ± 0.0454010035
Confidence Interval
8.56 - 0.0454010035
= 8.5145989965
≈ 8.515
8.56 + 0.0454010035
= 8.6054010035
≈ 8.605
92% Confidence Interval = [8.515, 8.605]
The graph of the linear equation y = 4x + 3 can be seen at the end of the answer.
<h3>How to find the graph of the given line?</h3>
Here we have the linear equation:
y = 4x + 3.
To graph it, we need to find two points that belong to the line, to do that, we evaluate in two different values of x. I will use x = 0 and x = 2.
When x = 0.
y = 4*0 + 3 = 3
So we have the point (0, 3).
When x = 2:
y = 4*2 + 3 = 8 + 3 = 11
So we have the point (2, 11)
Now we just need to graph these two points and connect them with a line. The graph of the linear equation is the one you can see below.
