Answer:
Mean:(137.2)
Median:(139.5)
Step-by-step explanation:
Mean = (125+136+150+119+143) divide by six(6)
= 823/6 = approx 137.2
Median = for the median, you will arrange the numbers in other. from smaller to the bigger number.
119,125,136,143,150, 150. so 136 & 143 is the middle number.
so you will add the middle number and divide by 2.
that is 136+143/2 = 139.5.
