Step 1
From the given data, we have: $\sum x = 0.63 + 2.12 + 23.18 + (-4.36) + (-4.31) = 17.26$ $\sum y = 22.05 + 53.1 + 116.6 + 154.8 + 204.1 + 222.6 = 773.25$ $\sum x^2 = 0.63^2 + 2.12^2 + 23.18^2 + (-4.36)^2 + (-4.31)^2 = 543.6858$ $\sum y^2 = 22.05^2 + 53.1^2 + Show more…

Noise levels at 3 volcanoes were measured in decibels, yielding the following data: 149, 163, 157. Construct the 95% confidence interval for the mean noise level at such locations. Assume the population is approximately normal. Step 1: Calculate the sample mean for the given sample data. Round your answer to one decimal place.
