Answer:
For this case the confidence interval is given by :
Step-by-step explanation:
Data provided
represent the sample mean for the fuel efficiencies
population mean
s=2.51 represent the sample standard deviation
n=601 represent the sample size
Confidence interval
The formula for the confidence interval of the true mean is given by:
(1)
The degrees of freedom for this case is given by:
The Confidence level for this case is 0.95 or 95%, and the significance level and and the critical value is given by
Replcing into the formula for the confidence interval is given by:
For this case the confidence interval is given by :
Answer:
Equation: 15 - f = n
Answer: n = 9
Step-by-step explanation:
The question is asking to write the equation. The equation would be
"15 - f = n" where f shirts folded
n = shirts remaining to fold
Then the question has gave us the value of f and has told us to solve it. Below is the solution.
15 - 6 = n
=> n = 9
Therefore, there is 9 shirts remaining after 6 of them are folded.
What did we solve?
We wrote our equation and solved what was required in the question.
I hoped this helped.
If possible... May I have brainliest :)

Answer:
<em>Step-by-step explanation:</em>
<em>Step 1. (The capture) Capture a sample total counted =958, and them back tagged counted=38,total tagged=56
</em>
<em>The idea is to estimate the proportion p = m/N of tagged =102.
</em>
<em>Step 2. (The recapture) After everything has settled down, capture a new sample of n fish. Count the number of tagged fish. Suppose that k of them are tagged.
</em>
<em>It is reasonable that, k/n would be a good estimante for p = m/N.
</em>
<em>Accordingly, for an estimate N of N, se solve the equation m/N= k/n.
