Question

benito is selecting samples of five values from the table, which row will result in the greatest mean?
population data
row 1 4 2 2 3 3
row 2 3 3 4 3 2
row 3 2 4 3 4 3
row 4 3 4 4 7 3
row 1
row 2
row 3
row 4

Explanation:

Step1: Calculate mean of Row 1

$\frac{4 + 2+2 + 3+3}{5}=\frac{14}{5} = 2.8$

Step2: Calculate mean of Row 2

$\frac{3+3 + 4+3+2}{5}=\frac{15}{5}=3$

Step3: Calculate mean of Row 3

$\frac{2 + 4+3+4+3}{5}=\frac{16}{5} = 3.2$

Step4: Calculate mean of Row 4

$\frac{3+4 + 4+7+3}{5}=\frac{21}{5}=4.2$

Answer:

Row 4
