Answer:
The mean will be increased by 5
Step-by-step explanation:
Suppose a set of data [tex](2, 4, 6, 8, 10, 12)[/tex]
Mean is defined as sum of all the values given set of data divided by total number of values.
Mean1 = [tex]\frac{2+4+6+8+10+12}{6} = \frac{42}{6} = 7[/tex]
Now if we add 5 toeach value, the new set becomes [tex](7, 9, 11, 13, 15, 17)[/tex]
for which,
Mean2 = [tex]\frac{7+9+11+13+15+17}{6} = \frac{72}{6} = 12[/tex]
Mean2 - Mean1 = 5
