In ANOVA, the total number of observations is equal to the sum of the number of observations in each group. In the ANOVA table, the error sum of squares (SSE) is calculated based on the difference between each individual observation and its respective group mean. Since SSE is based on N-k, where N is the total number of observations and k is the number of groups, we can solve for N by adding k to SSE and then rounding to the nearest integer. In this case, k=5 and SSE=308.1, so N=60. Therefore, the original sample size was 60.
