i need the correct answer

A production supervisor wants to verify the weight of the 5 kg rice that packed by two production lines. 5 sample of each production line has been selected and the reading of the weight has been recorded as below. Line 1 4.8 4.9 4.7 4.9 5.0 Lille 2 5.1 4.8 4.9 5.1 5.2 (a) Calculate the mean and the standard deviation of the weight of the rice that packed by production line 1 and line 2 respectively. (b) Which production line has more consistent weight of rice packed? Explain. (c) Construct a 95% condence interval to estimate the true mean of the weight of rice packed from production line 1 and line 2 respectively
