The dividing point between the sides is the equal sign. Standard equations are in the form of operations equal an answer (e.g., 2 + 4 = ___; 2 + 4 = 6; 2 + 2 + 2 = 6).

lana [24]

The <em><u>correct answer</u></em> is:

c)75.4 to 94.6

Explanation:

The formula for a confidence interval is:

\mu \pm z*(\frac{\sigma}{\sqrt{n}}),

where μ is the mean, z is the z-score associated with the level of confidence we want, σ is the standard deviation, and n is the sample size.

Our mean is 85, our standard deviation is 12, our sample size is 6, and since we want 95% confidence, our z-score is 1.96:

85\pm 1.96(\frac{12}{\sqrt{6}})=85\pm 9.6=85-9.6, 85+9.6=75.4, 94.6
