# S2 question help, hypothesis watch

1. on q6b, http://www.edexcel.com/migrationdocu...e_20100119.pdf

why is the lower critical value 2 and not 1, because on the tables, for 2, it is over 0.005 so it would be rejected. i thought you always pick the one which is smaller or equal to the sig level which is 0.005.

help.

P(X<=2)=0.002, which is less than 0.005.
