Yes/No b) Imagine that groups were combined into one group what is the Total Variation of that group? Total Variance = (state accurate to 1dp) c) Calculate 95% confidence intervals for the groups. (state limits to 2dp) Group 1 Low Limit = , High Limit = Group 2 Low Limit = , High Limit = Group 3 Low Limit = , High Limit = d) Conclusion
