A z-statistic of -1.34 falls between -1.96 and 1.96 (the critical values for a two-tailed test at the .05 level), meaning that it is not significant at the .05 level. It would also not be significant at the .01 level, as the critical values for a two-tailed test at that level are -2.58 and 2.58. Therefore, the correct answer is C, as the score is not significant.
