Final answer:
The mean, median, and mode for series (a) are 14, 6, 6 respectively, and for series (b) are 7.27, 2, 1 respectively.
Step-by-step explanation:
The mean, median and mode are measures of central tendency in a set of numbers. The mean is the average of the numbers, the median is the middle value when the numbers are ordered from least to greatest, and the mode is the number that appears most frequently.
For series (a) the numbers are 5, 5, 6, 6, 6, 9, 10, 10, 69. Mean=(5+5+6+6+6+9+10+10+69)/9 = 14; Median=6; Mode=6.
For series (b) the numbers are 1, 1, 1, 1, 2, 2, 4, 6, 6, 8, 48. Mean=(1+1+1+1+2+2+4+6+6+8+48)/11 = 7.27 (to 2 decimal places); Median=2; Mode=1.
