In [8] : expected_proportion_correct = expected_proportion_correct Out [8] : 0.5 In [9] : ok . grade ( "q1 2 ") ; Running tests Test summary Passed : 2 Failed : 0 [ ooooooooook 100.0 % passed The goal now is to see if our deviation from this expected proportion of correct answers is due to something other than chance In [ 10 ] : valid_stat = make_array (2) valid stat
