Conducting a two-sample t-test assuming equal variances with a significance level of 0.05, we get a t-statistic of -0.5 and a p-value of 0.6266. Since the p-value is greater than 0.05, we fail to reject the null hypothesis that there is no significant difference in preparation times with and without the slicer. Therefore, the best choice is B.
