Answer:
See solutions below
Step-by-step explanation:
For the set of datas
30, 12, 15, 14, 15, 24, 13, 18, 15, 27
Mean = 30+12+15+14+15+24+13+18+15+27/10
Mean = 183/10
Mean = 18.3
Median is the number at the middle after rearrangement
12,13,14,15,(15,15),18,24,27,30
Median = 15+15/2
Median = 30/2
Median = 15
Mode the value that occurs the most. According to the data since the number that occurs the most is 15, hence the mode is 15
b) For the set of datas
511, 503, 505, 505, 515, 491, 514
Mean = 511+503+505+505+515+491+514/7
Mean = 3,544/7
Mean = 506.3
Median is the number at the middle after rearrangement
491, 503, 505, (505), 511, 514, 515
Hence the median value is 505
Mode the value that occurs the most. According to the data since the number that occurs the most is 505, hence the mode is 505
