Statistics

1 The Earth is structured in layers: crust, mantle, and core. Arecent study was conducted to estimate the mean depth of the uppermantle in a specific farming region in California. Twenty-six,n = 26 sample sites were selected at random from anormally distributed population of approximately N = 1598sites, and the depth of the upper mantle was measured using changesin seismic velocity and density. The sample mean was 127.5 km andthe sample standard deviation was 21.3 km. Suppose thedepth of the upper mantle is normally distributed. Find a 90%confidence interval for the true mean depth of the upper mantle inthis farming region.
