Extracted text: In a famous laboratory it is suspected that the results from two barometers don not agree.Ten samples were tested using equipment A and corresponding samples were tested using equipment B. Determine whether there is a significant difference in the two systems at the 99% confidence level. The results are follows: SAMPLE NUMBER EQUIPMENT A EQUIPMENT B 1 72 73 43 45 3 54 56 4. 75 75 5 50 53 6 48 50 7 73 72 8 55 54 48 48 10 50 52
