Answer 1

Answer:

1. Mean = 36.125
2. Mean = 36.125Median = CAN'T BE DETERMINED
3. Mean = 36.125Median = CAN'T BE DETERMINED Mode = 10

Step-by-step explanation:

Mean

= Sum of observations ÷ no. of observations

= 10 +12 + 30 + 50 +10+70+5+90 ÷ 8

= 277÷8

= 36.125

Median

= n/2th obs.

= 15th obs

(NOT GIVEN)

Mode

= 10

since it occurs most no. of times (2)
