14.38 An extermination firm is testing several brands of pesticide spray, all of which claim to be effective against ants. Under controlled conditions, each spray is used on 10 ants of the species listed here. The measurement in each cell is the number of seconds until all 10 ants are dead. Given these data, and using the 0.05 level of significance, can the firm conclude the brands are equally effective? Using the appropriate statistical table, what is the most accurate statement that can be made about the p-value for the test?
