A dietitian wants to know the average time spent on breakfast in a primary school. The dietitian randomly samples 25 students an
blsea [12.9K]

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.

<em />

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:

E=\dfrac{UL-LL}{2}=\dfrac{13.232-11.968}{2}=\dfrac{1.264}{2}=0.632

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).
