TABLE IV (p. 11) 



Extension of the Table of the Probability Integral F-^(\-a). (Calculated 

 by Julia Bell, M.A., Drapers' Research Memoirs, Biometric Series, vm, p. 27.) 



It has been found needful occasionally to determine probabilities for deviations 

 exceeding considerably the limit x\a = 6 of Sheppard's Table II. 



Illustration. If ac/a = 34 31, determine to two significant figures the probability 

 of a deviation occurring as large or larger than this. 



The table gives us :
