Question 8 One online source claims that optimum moisture content (or, % water) of popcorn is 14%. Is there a statistical difference between this accepted value and group 2's data (xm = 9.4, sx = 2.2, n = 10) at the 95% confidence level? Conduct a t-test to find out (see Appendix I for the equation and an example and be careful there are two types of t-tests). t-value used: 2.09 Conclusion: Yes, the difference is statistically significant. Answer 1: 2.09 2.26 Answer 2: Yes, the difference is statistically significant.
