A study has been conducted to compare the anxiety levels reported by Australian adults across four different age groups (18 to 29; 30 to 39; 40 to 49; and 50 to 59). Anxiety was measured on a metric scale, with higher scores indicating higher levels of anxiety. Suppose the researchers hypothesised that there would be a significant difference between 18 to 29 year olds and 40 to 49 year olds. How would you set up the contrast coefficients for each age group to test this hypothesis? (note that the first group has been set as 1) 18 to 29 year olds = 1 30 to 39 year olds = %3D 40 to 49 year olds = 50 to 59 year olds =
