To find the value of (B) in the context of the ANOVA table, we need to understand the relationship between the total sum of squares (SS) and the sum of squares for the treatment and error.

In ANOVA, the total sum of squares (SST) can be calculated as follows:

\[ SST = SS_{\text{Treatment}} + SS_{\text{Error}} \]

Where:

  • \( SS_{\text{Treatment}} = A \) (the sum of squares for treatment),
  • \( SS_{\text{Error}} = 10,254 \).

Thus, we can express the total sum of squares (B):

\[ B = A + 10,254 \]

To find (B), we first need the value of (A). The mean square for treatment (MS_Treatment) is given by:

\[ MS_{\text{Treatment}} = \frac{SS_{\text{Treatment}}}{df_{\text{Treatment}}} = \frac{A}{2} \]

The mean square for error (MS_Error) is given by:

\[ MS_{\text{Error}} = \frac{SS_{\text{Error}}}{df_{\text{Error}}} \]

Based on your provided values, \( MS_{\text{Treatment}} \) is given as \( 43,024.778 \). Thus, we can use this to determine \( A \):

\[ 43,024.778 = \frac{A}{2} \]

Solving for \( A \):

\[ A = 43,024.778 \times 2 = 86,049.556 \]

Now we can substitute \( A \) back into the equation for \( B \):

\[ B = A + 10,254 = 86,049.556 + 10,254 = 96,303.556 \]

So, the value of (B) is approximately:

\[ B \approx 96,303.556 \]

Thus the value of (B) can be rounded to a suitable decimal place depending on context, typically:

\[ B \approx 96,304 \]
