13-50. Anarticleinthe FoodTechnology Journal(1956, Vol. 10, pp. 39-42) described a study on the protopectin content of tomatoes during storage. Four storage times were selected, and samples from nine lots of tomatoes were analyzed. The proto- pectin content (expressed as hydrochloric acid soluble fraction mg/kg) is in Table 13E-1. (a) The researchers in this study hypothesized that mean pro- topectin content would be different at different storage times. Can you confirm this hypothesis with a statistical test using a = 0.05? (b) Find the P-value for the test in part (a). c) Which specific storage times are different? Would you agree with the statement that protopectin content decreases as storage time increases? (d) Analyze the residuals from this experiment.
