I tried to solve this problem using spss results

please advise me what is wrong to my findings

1. Use the degrees of freedom from your SPSS output or if necessary, hand-calculate them using the formulas in your e-book. Using the Appendix in your e-book to find the critical value, and list it here (do NOT round - include all decimal places). Also label and state your obtained value from your SPSS output. Is the critical value SMALLER or LARGER than the obtained value from your SPSS output? Does this mean you REJECT or FAIL TO REJECT the null hypothesis? Does this mean the results are "significant" or "non-significant"?

my results

Df = 41

cv = 1.684

obt = -86.52

p=.001

cv > obt

Degree of Freedom is 41 and the critical value of F AT 0.05 level of significance =1.684 while F STATISTICS value =-8.652. The critical value is larger than -8.652. so we accept the NULL hypothesis. This shows the result is not significant which mean that ALL means are equal.
