Answer:

1.1264

Step-by-step explanation:

Given : An experiment using 35 guinea pigs is set up to study the weight of the pigs after injecting them with a drug.

To Find: If the population mean is 23.5 grams with a standard deviation of 3.4 grams, what is the margin of error of the sample mean?

Solution:

n = 35

$\sigma = 3.4$

Confidence interval = 95%. So, z =1.96

Margin of error = $z \times \frac{\sigma}{\sqrt{n}}$

Margin of error = $1.96\times \frac{3.4}{\sqrt{35}}$

Margin of error = $1.1264$

Hence the margin of error of the sample mean is 1.1264.
