There are three registers at the local grocery store. Eight randomly sampled waiting times are observed at each register. The ANOVA F-statistic obtained from the data is F=2.76181, with P-value = 0.0861305. a) Perform an ANOVA test at the 0.05 significance level. A. No sufficient evidence to suggest at least one mean is different from the rest. B. There is sufficient evidence to conclude that at least one sample mean is not equal. C. There is sufficient evidence to conclude that all means are not equal. D. There is sufficient evidence to conclude that at least one population mean is not equal. b) Perform an ANOVA test at the 0.1 significance level. A. No sufficient evidence to suggest at least one mean is different from the rest. B. There is sufficient evidence to conclude that at least one sample mean is not equal. C. There is sufficient evidence to conclude
