Suppose that you had collected the following sample data (in inches) on the diameters of tree trunks, measured at waist level and growing at 2000’ elevation in the Cascade Mountains: 9.0, 6.2, 6.5, 7.0, 10.5 and 8.8. If you assume that the data is normally distributed, then the reasonable range of values that you would expect to see in a 95% confidence interval for the population mean based on a typical sample of this size selected from this population of trees would be: (a) 5.85” to 8.95” (b) 6..22” to 9.78” (c) 6.58” to 9.42” (d) 7.17” to 9.25” (e) 6.75” to 10.18”

Suppose that you had collected the following sample data (in inches) on the diameters of tree trunks, measured at waist level and growing at 2000’ elevation in the Cascade Mountains: 9.0, 6.2, 6.5, 7.0, 10.5 and 8.8.  If you assume that the data is normally distributed, then the reasonable range of values that you would expect to see in a 95% confidence interval for the population mean based on a typical sample of this size selected from this population of trees would be:

(a) 5.85” to 8.95”
(b) 6..22” to 9.78”
(c) 6.58” to 9.42”
