Suppose a researcher is interested in understanding the variation in the price of store brand milk. a random sample of 36 grocer
liq [111]
The confidence interval extremities are given by the formula:
m +/- (z · σ / √n)

In your problem:
m = 3.13
<span> σ = 0.23
n = 36
The z-score for a 99% confidence interval is 2.576

Therefore:
</span>m - (z · σ / √n) = 3.13 - (2.576 · 0.23 / √36) = 3.031
<span>m + (z · σ / √n) = 3.13 + (2.576 · 0.23 / √36) = 3.229

Therefore, the confidence interval is (</span>3.031, <span>3.229).</span>
