If a calculated value of Chisquare of 9.07 is found, what decision should the researcher make? A. There is a significant preference at both the .05 level of significance and the .01 level of significance B. There is no significant preference at any level of significance C. There is a significant preference at the .05 level of significance but not at the .01 level of significance D. There is a significant preference at the .01 level of significance but not at the .05 level of significance
