Multiple Choice

A wildlife biologist wants to determine the mean weight of adult red squirrels.

Assuming these squirrels can be considered a random sample of all red squirrels which of the following formulas gives a 95% confidence interval for the mean weight of all squirrels?

• A) \( 12.32 \pm 2.228\left(\frac{1.88}{\sqrt{9}}\right) \)
• B) \( 12.32 \pm 2.228\left(\frac{1.88}{\sqrt{10}}\right) \)
• C) \( 12.32 \pm 2.262\left(\frac{1.88}{\sqrt{10}}\right) \)
• D) \( 12.32 \pm 1.96\left(\frac{1.88}{\sqrt{10}}\right) \)
• E) \( 12.32 \pm 2.268\left(\frac{1.88}{\sqrt{9}}\right) \)
