{24, 95, 76, 60, 15, 48, 80, 75} a. Mean = b. Median c. Mode =

sp2606 [1]

Answer:

a)59.125, b)67.5, c)None

Step-by-step explanation:

Mean = All values added up and divided by the number of values
$\frac{24+95+76+60+15+48+80+75}{8}$

Median = Put all numbers in order from least to most and use the middle one, if there are two, use the mean of those two
$15, 24, 48, 60, 75, 76, 80, 95$ . The middle ones are 60 & 75 so $\frac{60+75}{2}$

Mode = The number that repeats more times. In this case none of them repeat.
