Answer 1

Bom dia

a)

(1, 4, 0, 1, 8, 0, 9, 3, 4, 8, 3, 3, 5, 2, 7, 7, 2, 4, 0, 6)
{0, 0, 0, 1, 1, 2, 2, 3, 3, 3, 4, 4, 4, 5, 6, 7, 7, 8, 8, 9}

média, S = 77, n = 20, m = S/n = 77/20 = 3.85
mediana (3 + 4)/2 = 3.5 
moda 0 e 4 

b)

(30, 33, 34, 48, 35, 37, 42, 40, 34, 37)
{30, 33, 34, 34, 35, 37, 37, 40, 42, 48}

média, S = 370, n = 10, m = S/n = 370/10 = 37 
mediana (35 + 37)/2 = 36
moda 34 e 37 

c) 

(7, 6, 4, 5, 4, 10, 7)
{4, 4, 5, 6, 7, 7, 10}

média, S = 43, n = 7, m = S/n = 43/7 = 6.143 
mediana 6 
moda 4 e 7 

d) 

(3, 4, 10, 6, 9, 4, 6, 5)
{3, 4, 4, 5, 6, 6, 9, 10}

média, S = 47, n = 8, m = S/n = 47/8 = 5.875 
mediana (5+6)/2 = 5.5 
moda 4 e 6
