(a) 7.5
(b) 8.8
(c) 8.0
(d) 7.9
(e) It cannot be Determined.
2. The sample mean for this data is:
(a) 4.8
(b) 8.0
(c) 7.9
(d) 6.5
(e) None of the Above.
3. The sample standard deviation for this data is:

5. Based on your answers to questions 2 and 3, if you assume that the data isnormally 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”
(c) 7.9
