Using the data below, can you explain how to solve Q1.1 and 1.2?

53 Suppose you conducted a study trying to determine whether the contents of 54 sugar are different between two different manufacturing plants of your sugary 55 drink. To collect a sample you have to unkeg a large quantity of the liquid 56 which then can't be sold so you need to limit your study to as few samples as 57 possible. This is not your first time conducting this experiment so you know 58 the standard deviation of sugar content will be around 15 ppm. You opened the 59 same number of kegs from both manufacturing plants. 60 61 You observed the data below: 62 63 - {r Q1data} 64 01
