The graduated rates have been produced using the parametric formula method - a formula with 3 parameters has been fitted to the crude rates. The deviations of the observed number of deaths from the expected number of deaths at each age have been calculated. You have: Number of positive deviations: 41 Number of groups of positive deviations: 16 Carry out a grouping of signs test on these graduated rates and state your conclusion. [6]
