Answer:

The margin of error associated with the true population mean is;

[tex]\pm4.652\text{ ounces}[/tex]

Explanation:

Given the sample size as;

[tex]n=30[/tex]

standard deviation as;

[tex]\sigma=13[/tex]

the mean;

[tex]\bar{x}=33[/tex]

And confidence interval of 95%;

[tex]Z=1.96[/tex]

The Margin of Error MOE, can be calculated using the formula;

[tex]\text{MOE}=\pm Z\times\frac{\sigma}{\sqrt[]{n}}[/tex]

Substituting the given values;

[tex]\text{MOE}=\pm1.96\times\frac{13}{\sqrt[]{30}}=\pm4.652[/tex]

Therefore, the margin of error associated with the true population mean is;

[tex]\pm4.652\text{ ounces}[/tex]
