Plug in 2 wherever you see 'a'

3(2) + 5(2)(2)

1. 3×2 = 6, so:

6 + 5(2)(2)

2. 5×2=10, 10×2=20, so:

6 + 20

The final answer is 26.

n studying the sampling distribution of the mean, you were asked to list all the different possible samples from a small populat

Mashutka [201]

The Total outcome with replacement will be given by ,3² = 9, the mean of the samples will be 2 , 4.5 , 3 , 7 , 4

Mean predicts the central tendency of a data set , It is determined by the ratio of sum of all the numbers to the total numbers in the data set.

On the basis of given data

The number given is 2,4,7

Size of the sample = 2 with replacement

The Total outcome with replacement will be given by

3² = 9

Possible outcome can be

2,2 2,4 2,7 4,4 4,2 4,7 7,7 7,2 7,4

The sample mean can be calculated as

(a+b)/2

(2+2)/2 = 2

similarly the mean of the samples will be 2 , 4.5 , 3 , 7 , 4
