Question: The sample data and the scatter plot was not added to your question. See the attached file for the scatter plot.
Answer: Yes
Step-by-step explanation:
From scatter plot, it was discovered that there is a linear relationship between the two variables and both variables are quantitative.
Therefore, it appropriate to use the correlation coefficient to describe the strength of the relationship between "Time" and "Fish Quality"?
Answer:
The right options are:
a. The margin of error is 0.632
f. There is a 95% chance that the true mean is between 11.968 and 13.232 minutes.

Step-by-step explanation:
<em>The question is incomplete:</em>
<em>Select one or more:</em>
<em>a. The margin of error is 0.632</em>
<em>b. The margin of error is 1264.</em>
<em>C. The margin of error is 0.600.</em>
<em>d. We believe that the true mean time spent on breakfast is between 11.968 and 13.232 minutes.</em>
<em>e. If we take many other samples from this population, 95% of them will have a sample mean that is between 11968 and 13232.</em>
<em>f. There is a 95% chance that the true mean is between 11.968 and 13.232 minutes.</em>
The margin of error can be calculated from the bounds of the confidence interval as:
As the confidence interval is calculated at 95% confidence, we are 95% confident that the true mean is within the calculated interval. We are not 100% confident although (that's why Option d is false).
This interval does not give us information about the sampling distribution (option e is false).
