vodomira [7]

Answer:

Step-by-step explanation:

Mean & median of 6 packages:

15, 17, 19, 31, 33 , 35

Median = $\frac{19+31}{2}$

= $\frac{50}{2}$

= 25

$Mean = \frac{15+17+19+31+33+35}{6}\\\\=\frac{150}{6}\\=25$

Mean & median of 7 packages:

15,17,19,31,33,35,39

Median = 31

$Mean=\frac{19+15+35+17+33+31+39}{7}\\\\=\frac{189}{7}\\\\=27$

After including 39 ounce package, Median will increase more
