Why is the answer 2? Like where do you get it from the table?

Acidity levels (\'Response\') are measured for samples of three different types of coal (\'Type of Coal\'). Three different concentrations of ethanolic NaOH (\'NaOH Conc.\') are used to make the acidity determinations. Use the JMP output below to answer problems 6-12. (Use alpha = 0.05.) The number of replications (K_ij) used in this experiment is: cannot be determined from this output. K_ij differs depending on the values of i and j. K_ij = K = 2. K_ij = K = 1. none of the above.
