    Answer:

    6.80kg, 6.70kg and 6.90kg.

    Explanation:

    To get the set of measurements that best represents accuracy if the true value is 6.80 kg, we will find the mean of the set of numbers and chech which is equal to 6.80kg

    According to the set of data 6.8kg, 6.7kg and 6.9kg

    Mean = sum of the number/sa mple size

    Sum of the numbers = 6.8+6.7+6.9 = 20.4

    sample size = 3

    Mean of the set of measurement = 20.4/3

    Mean of the set of measurement is 6.80kg

    Since the answer is 6.8kg, hence set of measurements that best represents accuracy are 6.80kg, 6.70kg and 6.90kg.
