Elena L [17]

Answer:

C) $826.82 to $873.18.

Step-by-step explanation:

Sample mean (M) = $850

Standard deviation (s) = $54

sample size (n) = 36

Z for 99% confidence interval (Z) = 2.576

The confidence interval is determined by the following relationship:

$M \pm Z*\frac{s}{\sqrt{n}}$

Applying the given values, the lower (L) and upper (U) values are:

$850 \pm 2.576*\frac{54}{\sqrt{36}}\\L=\$826.82\\U=\$873.18$

The answer is C) $826.82 to $873.18.
