A)There is no basis for concluding that mean sales is different for the different days of the week.
B)Based on the p-value,the null hypothesis should be rejected since the p-value exceeds the alpha level.

The output does not provide a significant result as the p-value (0.17) is greater than the 0.05 significance level. Therefore, we fail to reject the null hypothesis, and there is no basis for concluding that mean sales are different for the different days of the week.
