Answer #2

Solution:

Given that,

1, 3. 4, 4, 6, 13, 14,17, 19

n = 9

a)The mean of sample is   

x/n =  (1 + 3 + 4 + 4 + 6 +13 + 14 + 17 + 19 / 9)

   = 81 / 9

= 9

The sample mean is = 9

b ) Median = Median is middle most observation of data set,

1, 3. 4, 4, 6, 13, 14,17, 19

Median = 6

c) Mode = Represent the repeated value in data set,

   1, 3. 4, 4, 6, 13, 14,17, 19

Mode = 4

d) The shape of distribution is right skewed distribution, because mean > median > mode
