No, there is no sufficient evidence because the average weight (49.7 kg) of 20 random sacks of rice is within the confidence interval.

No, there is no sufficient evidence because the confidence interval is just slightly lower than the labeled weight (50 kg).

Yes, there is sufficient evidence because the labeled weight of the sacks of rice is not within the constructed confidence interval.

Yes, there is sufficient evidence because the average weight (49.7 kg) of 20 random sacks of rice is obviously lower than their labeled weight (50 kg).
