Question: An index of flavor was used to evaluate the effect
An index of flavor was used to evaluate the effect of adding dioctyl sodium sulfosuccinate (DSS) to milk to stabilize its flavor. Four DSS levels (in parts per million) were used, including no DSS, and the milk was stored for 7 weeks and 28 weeks to observe the effect of DSS level on storage time. Milk from four different sources (replicates) was used. Use an appropriate computer program to perform an analysis of variance to determine the effects of DSS, storage time, and their interaction, using the 0.05 level of significance.
Answer to relevant QuestionsPerform a multiple-range test to determine the nature of the differences among the three detergents in Example 15.1. Use the 0.01 level of significance. Perform appropriate multiple-range tests, using the 0.05 level of significance, to characterize the differences among the DSS-level means and the storage- time means in Exercise 15.30. Use statistical computer software to test for the significance of all estimated main effects and two- factor interactions at the 0.05 level of significance. A random sample of size n = 2 is taken to test whether a normal population has the mean µ = 0. (a) If the observed sample values are x1 and x2 with x1 > x2 > 0, show that the statistic for the one-sample t-test can be ...The following are the amounts of money (in dollars) spent by 16 persons at an amusement park: 20.15, 19.85, 23.75, 18.63, 21.09, 25.63, 16.65, 19.27, 18.80, 21.45, 20.29, 19.51, 23.80, 20.00, 17.48, and 19.11.
